All I can say is WOW. He sent me 2 black brackets [one split for wiring,one solid] at no cost for the parts or the shipping. I used the split version since my wiring was already installed and it went on in minutes,nice,tight and secure. A very cool way to get rid of the bulky Triumph stuff and the perfect end to a crappy work day. :upthumb:

sweatmachine -

Appreciate the comment, thanks! - if you already have a mini gauge or a set of mini gauges - and it's the same one or ones as rodburner's, bonneville billy's or loxpumps (the cans mic out to 2.39" OD, from Mikes XS, also apparently available from a source on ebay) - I'll be happy to fix you up, send me a PM and let me know if you want a solid single gauge bracket, a slotted single gauge bracket, or a R/H - L/H set.

Prototyping the R/H - L/H set for Lox's bike right now, hopefully we'll get them fitted this weekend and post some pics. However, I haven't found a good way to slot the R/H - L/H set to slide wires through and maintain the needed super-tight fit (brackets are .125" aluminum with fitted neoprene gasket) so if the gauges are already on, they would need to have wires undone, slipped through the R/H - L/H brackets, and then reconnected.

If you're going single gauge and are already wired up, then the slotted single bracket is probably the way to go - likewise, if you're going single gauge but not yet installed, I'd recommend the solid single
bracket - keep in mind, these mini gauge brackets are still very much in prototype stage - hope to hear good road test results on the slotted single from rodburner... ;-)

No pics on the L/H - R/H set just yet - this weekend hopefully - keep ya posted...



Nice pics! and you're welcome...

sweatmachine... planning on making a couple of sets in the next week or
two... will definitely send a set your way... pm me with a shipping addy...

Much cleaner than stock, D9, how do I get a pair?

Send me a pm with shipping addy - fyi, have not worked out a price for these, still a fun, labor of love kinda thing - costs should be pretty minimal though.

For anyone else following this thread... coupla things I'd advise... happy to make a set for anyone who either has already purchased or is seriously considering installing the 2.39" OD mini-gauges - but if you haven't gone that far yet, not sure if you're gonna, or are for any reason still on the fence, probably just best to wait until you've made your purchase and have your gauges in hand... no interest in making parts to sit forlornly on a dark shelf somewhere... hope ya'll understand.

Likewise, if you already have your gauges and want the brackets, don't wire the gauges up yet, 'cause you'll have to unwire them to push them thru the brackets...

Please note, currently these brackets only work with the 2.39" OD mini gauges (ones on Mikes XS state 2.25" diameter, but the outside of the cans calipered to 2.39" on Lox's & same with rodburners...)

Also happy to consider designing and producing one-off custom bracket sets if anyone is feeling particularly creative - send me a pm.

Appreciate the comments - pm me with a shipping addy, I'll get one out to you - small production run should be shipping about two weeks or so...



I have the speedo from mikes already wired up, my bracket kinda sucks, I wouldn't mind one of the ones you made. It looks a lot better than mine. What would I need to do to get my hands on one. I don't need the slotted one cause I can just disconnect the wiring harnes.

You nailed it - great observation, from someone who's obviously been poking around on this like some others in here...

The stock bracket bosses are the real obstacle - and it's a bit of a visual Catch-22... if you don't use the existing bosses, they'll just sit there an look funky, unless you remove them... if you do use the bosses, the choices seem to be either a push through solution like what I've come up with - or - a slick, thinner-gauge little bracket that uses the bosses but then makes a couple of tight, well managed bends to arrive underneath the
gauges - the second solution might look better than the push-through, but that's another project...

Another possible mounting point - again, probably visually better than the push-through solution - is to use two holes that are located underneath the upper triple clamp - you can see these holes in the reflection in the headlamp of the underside of the upper triple clamp if you look carefully - Lox seemed to recall these holes were used for windscreen fastening - a simple V-bracket might work splendidly here and get the gauges - even the stock gauges - further inboard and also lower - but thats IF you're willing to grind off the existing bosses...

Another possibility - using the lower handlebar clamp bolts - still would need to remove stock bosses...

Several posters have mentioned using the fork tube bolts for gauge bracket mounting points - I never had mine apart, so I'm not sure if that's a possibility or not - anybody who can shine some light here, please consider weighing in...

Couple of pics, courtesy of Loxpump, bosses circled in red, for anyone just joining the thread...

I'm also curious to see what can be done to improve the position of the stock gauges, though I'm sure that you'll have quite a bit more room to play with than the rest of us, having already lowered your light. Mind you, those mounting lugs on the yoke come up a fair way and, if you went the way of mounting the gauges from bellow the yoke, the coresponding holes in the lower surface come in at a pretty sharp angle and there would still be the upper lugs to tidy up somehow - short of a bit of grinding and powder coating. I look forward to seeing what you come up with.
Meanwhile, I'd still love to see if I could incorporate an oil pressure and/or temp gauge into the face of the tach somehow (in a similar way to which the lights are mounted within rod's and lox's speedos).

Thanks for posting details of the install - excellent feedback, was wondering if anyone had gotten theirs yet, all brackets shipped out Monday 11/20... the single biggest concern I've had about these is... will the mikes XS gauge ODs be consistent? I had my fingers crossed they would be and now I know, they're not... which is good info to have going forward.

If you have a caliper and can take a tight measurement on both gauges, it'd be helpful for me to know exactly how much the OD variance is...
A little bit of tape will probably work fine, but I'm already considering if thin gauge flexible shim stock to fit in the .125" center channel of the gasket would solve the loose fit easily and invisibly... can't see why that wouldn't work, & I could just send shim material along with brackets... going to head down to the shop now and see what I have...

* * * * * *

Ok, I think I've got it - found some strips of modelling brass - it's probably too thick, mic's out to .03... easily bends to the ID of the
gauge - it's also too wide, 3/16" and I need 1/8"... but with 1/8" wide material of sufficiently thin gauge, this looks like it could solve an undersize OD condition... got this strip from a hobby store... here's a pic just to get the idea...

Got me thinking, what if a gauge is too big or slightly out of round? That's probably easier - take off the gasket and carefully file or sand the opening little by little, checking fit periodically... it's aluminum and it's easy to work with...

Meanwhile, thanks again for posting so soon - will send shim material to you as soon as I have it...

I didn't waste any time at all putting the bracket to use, when it showed up in the mail today.
The tachometer I have is a couple of thousands' smaller than the speedometer, so I'm going to have to build up the bracket on the tach side somehow. A couple of strips of aluminum speed tape might work on the inside of the bracket, put the rubber grommet back around the bracket and I should be good to go. I have to think about it overnight...

For the record, I didn't get the tach from MikesXS... I just got it off of ebay, so who knows where it's from - and it was used, to boot.

Even .003 may be too much. There is very little difference between the speedo size and the tach size - I'd guess about .0015. I work today and tomorrow (wouldn't you know, the weather's great...). I'm gonna try some aluminum speed tape at a couple of points along the inside of the bracket Monday morning. Then, I'll replace the rubber grommet over the bracket - that should keep the aluminum tape from sliding off the bracket - then, replace the tach in the bracket frame.

I'm gonna get a caliper too - enough guessing.
The speed tape will probably work fine - I may be going overboard with my shim fix - keep me posted - btw, got a great digital caliper at Harbor Freight of all places, I think it was less than $20 - once you have one, you'll wonder how you got by without it.

."Hey D9" How about a bracket design that holds the gauges and also fits the stock lights?
But seriously folks... was working on that very thing a bit late last night - the stock indicator lights are nice looking pieces, was thinking how they might look arranged vertically between the smaller gauges... plenty of ideas in the works, perhaps too many...

It's just too darn easy to arrive in a "what-if" state of mind when contemplating the Bonneville. I'm obviously not alone in this...

While on the subject - hope member Mancha will not mind -
but check out his beautifully done Thruxton gauge bracket, which uses stock gauges and drastically improves the look of the bike... nice work indeed!

Manchas cool Thruxton gauge bracket

Just goes to show you, lot of possibilities out there...

Outstanding work D9 ;man do I ever want a set!
meatwagon -

Thanks, very much appreciate the comment - send me a pm with shipping addy & pick your poison - here's what's left from the initial production run:

4 single gauge brackets - "the rodburner special":

4 two-piece dual-gauge bracket sets - pic of loxpump's setup:

1 one-piece dual-gauge bracket (black) - pic of psasak's setup:

Wow... thanks for posting that, had no clue the rubber grommet could cause a glitch like that- good to know!

Also - got ahold of some tough aluminum foil tape w/permanent adhesive,
it's about .003"... can I send you some 1/8" strips? Easy to apply to the inside edge of the bracket once grommet is removed, easy way to close up the ID for a tighter fit on the tach... also now have some thin (.001) polycarbonate film I can cut into strips - much fussier to work with than the tape, you have to push it into the flat channel of the grommet, but once pushed into place and grommet reinstalled, it should effectively and incrementally reduce the ID.... let me know, I'll send some out to you.

Thanks again for the update - & good video too - bike sounds & looks great!

FedEx just dropped off the gauges from Mike's XS. The speedo (part # 03-0748) is labeled M=2.1, which I assuming means the ratio is 2:1. I was lead to believe that the NTB uses a 2240:60 ratio drive. The tach (part # 03-0732) is labeled 1=1.5.

Has anyone installed the Mike's speedo and is it correctly displaying speed?

BTW... great service from Mike's. Fast shipping and the parts were about $1 less than my wholesale cost from other sources.

And the D9 brackets: way cool!

Good question... Here's an email sent to Mike at mikes XS with his response:

Great web site!

Question: Are all of your 2.25" diameter speedometers 2:1 ratio, or are any of them 2240:60 ratio?

All japanese speedos are 2240 RPM = 60mph


RaceDweeb, glad you like the brackets!

Man, that looks like it was meant to be - good work!

Here's my quick addition to my dual mini gauge setup. I was home all day today when my box from NB came in the mail, what luck. Not much else to do when there's freezing rain coming down.

I just straightened out the bracket that came with it and used one of the bracket bolts. A little black paint at the bracket will disappear.

Just got a new(er) tach - one with only one wire bundle coming out of the back. It says "YIH TYAN" on the bottom of the face. It must be a couple of .001 bigger, because I had to take my speed tape off of the bracket. Now, it fits as tight as the speedometer.

... but it's snowing... :(
Phil - just curious - is the new tach from Mikes XS?
If it is, can you post the part #...?

Glad it's a good fit, wherever it came from...

I would have preferred a 8,000 rpm tach.


MIke - looks awesome - wow! The aluminum bracket looks like
it matches the triple clamp - did you anodize the bracket or does it just
look that way in the pic??? Agreed re the 8K tach...

Phil - confused, I am - apologies - apparently Mikes XS mini tachs are mechanical and will NOT work on the NB...?

Hey Terry - got a link for Baron?

Looks great! I believe you've posted the first pics with the brackets
on a Thruxton - cool!


Any problems installing?

How the heck did you get that reset knob off the trip odo??? You had to
have removed the knob, shaft & rubber seal to get the speedo fully seated and then reinstalled the parts once the speedo was in...?
Sure looks better that way - please hip me to your method...

Can you still reach the knob ok even though your reaching under
the bracket???

Thanks again for posting the pics!



:-D :-D :-D

Well, shoot... that explains it... oops...

rodburner -

I came this close to emailing you sunday and asking you to
check clearances for exactly that - a knob slot (does that
sound sleazy or what) - instead, went over to lox's house and put one of the protoypes over his speedo & drew the knob position right on the plastic.

What I'm thinking about is adding is a slot and then a second 1/8" retaining ring... slide the speedo through and then rotate, just like you said, but then, rotate the second ring into place... the ring would have a raised tab to match the gap in the slot... anyway, working on it!

But, may be moot as far as Bonnevilles are concerned - as you've pointed out, the little gauges are a good height just as they are - much lower could well be too low - other issue would be speedometer cable clearance - would probably have to move the gauges further apart...

It's all in the details...

Not sure if anyone's still interested in this thread- it's 4 months old, but I want to make some custom brackets for a tachometer- but not the mini one. I want to keep my regular sized speedo and get a regular sized tach that matches it, then make some brackets to install the speedo and tach right over the forks, like this:

My question is does anyone know of a source for tachometers of the same size as the stock bonnie speedo?
Granitsky -

Good to read your comment - you're not alone, others have suggested some brackets that do exactly as you've pictured, suspending the gauges apart, using the fork bolts like some of the older Bonnies... agreed, it would look cool!

Couple of things to keep in mind - choices of tachs & speedos for the Bonneville besides the stockers include minis, mini-mini's, some really cool high-end stuff, and whatever you can make work... :-D .

Question - are mini-gauges out of the question for the project? They look somewhat closer
sizewise and stylistically to the gauges in the picture you posted than the stock gauges do... let me know if you'd consider going this route, I may have a couple of these brackets left...

Meanwhile, back to the fork bolt-mounted bracket concept... one puzzle that has yet to be solved... the existing fork bolts seal the forks... because of their design, I'm not sure you could hold a bracket down with the OEM fork bolts
while maintaining a seal without getting into more involved machining of the brackets... there's fine threads, spacers and O rings under there... Loxpump has suggested drilling and tapping
a small hole into the top of the existing fork bolt and running a fastener through the bracket into that hole...

Say you had the custom brackets fabricated and had solved the sealing issue/fastening method... routing of the speedo cable would need to be
worked out, as of right now the position of the headlight bracket right under the speedo looks like it might not allow the speedo cable to connect. Are you ok with rotating the speedo CCW - 30 degrees or so - to allow attachment of the speedo cable?

FYI - new "lay-flat" bracket due out soon, uses stock tach, speedo & indicators... far different from what you're searching for, but may be
worth considering, here's a pic...

I just wanted to use the stock speedo just because I like having the original mileage on there. I figured I could use mini's or something similar to replace it if I had to.

My idea for the brackets was to just make/have made a bracket that extends outward more toward the forks, but uses the stock 4 connection holes between the forks, sort of like the split brackets you have, but that extend more outward...
Ok, I get it now - thanks for the explanation! I hear you about mileage.
It's all doable, but considering the overall bulk of the stock gauges, I still think you might be happier with the mini's... no time to post further this morning, but I have some possibilities for you... more later...
