i'll post this in tech thread as well as i'm not sure which one is most appropiate but anyway...

been putting out the feelers for all black tubeless spoked wheels for my 2010 mag bonnie. so far i've had a reply from alpina- not looking good- i thought the front wheel would cause some issues as it's not listed but in fact it's the rear that seems to be causing some head scracthing (i -foolishly?- assumed the 17" rear would be a pretty universal fit accross the range)

anyway- doug a the devon wheel company has been very patient and helpful with my enquiries. i'm keen to keep the 17" front and rear and am very happy with the handling characteristics - minus the occasional tendancy to track in the grooves of a crappy road-

but i do like purely on the aesthetic level the look of a fatter rear on the bike- but not enough to compromise the handling.

doug has suggested a 17" x 3.5" front and and 17" x 4.25" rear.

what do you guys think? - a good solution/ combination to tick all my boxes? - it's not an area in all my years tinkering and riding i've really experimented with so i'm really trying to gather as much info as i can.

and taking into account the large amount of cash i'd be dropping on it i guess i'm being a bit cautious/hesitant to leap in blind!!!

i'd never really planned to afford something like this- as soon as the salt trucks hit the road i was just going to whip the mags off and powder coat!!

thanks in advance!!

Yes that’s the correct size in my opinion and the ones I intend to purchase when the funds are in place... I had the Talon hubs sent to me from Doug in order to make the measurements for dish and spacers etc as they where originally designed to work withthe older style Bonnies... The rear fits straight on and the front just needs spacers made as the speedo drive is on the opposite side... You will also need a new disc..... Quality product though and will look the beanz with stainless spokes... Let me know if and when you have them and post some pictures –]

those sizes are perfect, what triumph should have used as 120-70-17 front is sportbike size offering many tire choices and the rear is perfect for the 150-70-17 which is offered everywhere as well, they would be my choices. i would not be afraid of installing a tube with radial on a wired rim if necessary since ducati also seen fit to do so on their sport classic rides

thanks for the replies guys

just had an email back from doug- as you say boycie a new disc is required up front but rear uses stock

doug says that black spokes and nips add around £100 to the overall cost- and i'm actually inclined to agree that black hubs and rims look good with stainless spokes.

these come with nickel plated brass nips- stainless are an extra £12 per wheel. i'm guessing the only difference is s.s nips are shiney?? (not a concern- in fact a put off!)

these can run tubes or he can do them tubless at £74 per wheel but would need to fit tyres- what do you reckon? - whats going to make my life easier- running with tubes or going tubless- are there any headaches to take into account in terms of tyre changing or maintenace going tubless that i'm not aware of or do you treat them the same as mags?

sorry for the questions and dithering- but it's an area i'm new to and a hefty dent to the wallet so want to be sure!!!!!

-incidentally boycie on a mag wheel front did you powder coat yours?

cheers guys!

boysie

Yes I powder coated them which has made me dither about spending so much on new wheels..... I do think it would improve the looks of the bike and allow a greater choice of tyres though.

In my research a 17" x 3.5" front and and 17" x 4.25" rear makes sense and provides a good choice of rubber. I also note some others have had lots of success with this wheel combination in Carrozzeria (not available anymore). I am leaning towards Kineo wheels for my 2004 Thruxton to reduce wheel weight although there are some issues such as speedo calibration and fitting a lower front mudguard with a 17 in front and offset with a fat rear. For these reasons I am likely to stick with OEM sizes as I like the nimble handling of the thinner wheels. If I stay 'thin' in Kineo then I am limited to Speed Demons, GT501 and perhaps BT45's in the OEM size

I have wheels from Doug @ Devon Rim Co. They are top quality items. 3.5inch front 18" diameter and 5.5inch rear. Black anodised,Talon hubs (black) and stainless spokes. I run tubeless tyress 120/70 & 170/70. I changed from a T100 disc to a Thrux disc and the wheels popped right in.They have transformed my bike along with the Maxton suspension front and back. The wheels save over 6kg in unsprung weight.

Having been to Doug's workshop I most highly recommend the guy and his wheels.

Oh, neat thread. I too, am considering Alpinas.

What's the weight of the Devon rims? Stock?

Thx

jotadude

Can't recall exactly but I do know weighing the wheels complete with tyres there was just over 6kg saved from the standard wheels with tyres. I think the 6+ KG appx 13lb was both wheels. I am sure if you email Doug at Devon Rim Co he has the answer

We{wife and I} have Dougs wheels and run them tubless with no probs I think its much safer this way, no sudden flats,{i hope}.
