I won an sv650 front wheel on ebay, and bought forks, axle, and complete brake system including the rotors, calipers, brake lines, and master cylinder/lever etc from an SV650 forum.

the forks are the same diameter as the bonnies, and all the dimensions are basically identical with the exception being the bonnie trees are .5'' narrower than the SV's.

I think I'll have to have the axle spacers turned down 1/4'' or so, and also play with the rotor & caliper spacing but other than that I think it'll be easy enough.

The rear wheel should fit fine too, provided the axles are the same size...which I'm going to just guess they are. :-D We shall see.

I'll have to flip the rear wheel around to put the cush drive on the right and the brake on the left, and also I need to figure out what size chain the SV uses to see about sprockets. These wheels are symmetrical so it will still look ok.

I saw Thrux-ton-up's post about 17'' wheels, and Rodburner's post about never losing any air in his Dymags...and I rode my brother's SV this weekend... Dual discs rule.

I'm thinking the whole ordeal can be done for under a grand. I'm in the hole about $500 now and all I'm missing is the rear wheel, but I'll likely have to buy tires and a chain, maybe some sprockets too, or do some drilling/fabricating adapter plates...

Gotta figure out how to drive the speedo too. Anyone know how the SV speedo is driven?

I want some rearsets too, and I was all ready to buy some and the SV idea came to me. I say idea, but it's been more like an obsession for me for the last 3 days...all I can think about. If I can make it work, and I think I can, I may sell off my bonnie parts (forks and wheels and brakes) here to cover the costs. I'm sure there will be takers.

Stock SV650 chain is a 525, but a lot of people go to a 520 chain to shed some weight. Not sure if anyone makes a 530 rear sprocket for an SV650, but someone like Sprocket Specialists should be able to do just about anything.

Speedometer drive is off the front hub, the standard worm gear and flexible shaft setup.

Stock SV forks are noted for their cheesy, primitive damper rod setup. First thing to do is to change out the fork oil, the stock stuff tends to be pretty watery. I've gotten excellent results with Race Tech's Cartridge Emulators and stiffer springs (the stock springs are just about perfect for a 130 pound rider).

Note that all of this information applies to a first gen (99-02) SV, the 2nd gen stuff may be somewhat different.

Why not try to adapt the entire front end, before you start making spacers, etc?
It may be as simple as getting a different set of stem bearings.....I'd investigate that possibility first.

as for the SV speedo.....I'm thinking that was an electronic unit with a hall effect sensor in the tranny.....but I could be wrong....don't hold me to that.

Looks Great Jeff - I'm with Kliff - try to adapt the front end as is - modify stem/bearings to make it fit. Having the forks a little wider is a good thing.


Ditto. Have the wheels powder coated silver. This set up is how the Bonnie series should be optioned.

IMHO the SV650 forks are no better than the Bonevilles.

On the SV650 forum I frequented when I had my SV650 there were more people wanting to mod or change the front forks than on the Bonnie forum.

They are more pogo than the Bonnies and often have annoying knocks. All this was acceptable as part of a cheap bike, but they are not great.

I thought about using the whole front end and modifying the stem and/or bearings to make it work but I wouldn't be able to use my stock bonnie controls as they're 1'' and the sv is 7/8''.

If I have to I'll get all new controls but I'd rather not. I'm going to see how it works with the bonnie trees first, then if if doesn't work out I'll grab a set of SV trees.

ChrisV, I'm sure the stock SV forks are probably as bad as the stock bonnie forks and that's ok. I'm more after the 17'' mag and dual disks, besides the aftermarket parts for the SV forks are more plentiful and cheaper than the bonnie parts.

Sweat, you have riden a sv correct? How did the front suspension compare to the bonnies when you rode it?

I think the difference in opinion could be the riders, most people with the bonnie aren't after the sport feel in the bike and the majority of sv riders are after a more performance oriented type ride. I mean look at the sv, it screams "thrash me, I like it".

Sweetdude. Why not use the Thruxton hand controls. They are 7/8", and the Tommaselli goose neck clip ons?This move would make more sense and allow you to graft the complete SV front end to the Bonnie. Just a gear heads thoughts.

I've ridden 2 different SV650s about 20 or 30 times. My brother has one, and my best bud has one too. They handle and stop much better than the bonnies. This could also be due to the fact that they're 100 lbs lighter than the bonnies, but the turn in, responsiveness, and flick-a-bility is leaps and bounds ahead of the bonnie. I think it's due to different geometry and 17'' wheels, oh that and a 'modern' design.

We're both wrong- it'a a hall effect sensor on the front hub. The GSXRs run 'em on the countershaft. But it's definitely got an electronic speedometer, not a mechanical one.
