Hello all. My name is Robert and I am new to the forum.

A friend of mine has a set of 17" Excel SM wheels I am interested in buying.
The hubs are stamped Kawasaki R-1237 on the rear, and Kawasaki F-0037 on the front. The rear rim width is 4.0" and the front rim width is 3.0".

After doing some research, I've found the R-1237 hub to fit KDX,KLR and KLX and the F-0037 hub to fit also fit the KDX and KLX. The rim widths are the exact same as those on the KLX250SF.

My question is, will these hubs mount to my existing axles and accept my stock brake rotors and rear sprocket, or will I have to respoke these wheels using my hubs?

Also, what other modifications would I have to make as far sprockets/gearing to achieve optimum commuting around town?

The only other information I have is that the rear sprocket on these wheels is a 38 tooth and the wheels themselves are 36 spoke.
The tires on the rims are 140/70R17 rear and 120/70R17.

Should I assume these wheels are off a KLX250SF and will be a direct swap, keeping in mind I will need a shorter kickstand and the other klx250s to klx250sf conversion necessities?

If there is another thread with this information, please point me in the right direction. Otherwise, any information regarding this application will be greatly appreciated.

Thanks for the help.

Regards,

Robert

 

the front wheel will give you problems with the speedo drive, if the wheels are cheap enough you could machine the front hub to take the 09 drive?
O' and Hi, Welcome to the forum

 

Pete, thanks much for the reply.

What do you know about the rear wheel? Will it fit my bike?

I was wondering what kind of machining is involved for the drive?
Would I need to counterbore the hub so the speedo drive is recessed into it or drill out for axle clearance?

If anyone else has input on the fitment of these wheels, please let me know.

 

Pete,

The hubs are stamped Kawasaki R-1237 on the rear, and Kawasaki F-0037 on the front. These numbers are the exact same on my 2009 KLX250S.

Are you sure the front hub will require machining to accept the speedometer drive?

I bought some hub (front and back) for my 09, the front needed the diameter of the speedo drive turned down (can't remember the size) an two pins fitted to connect with the 09 speedo drive so it would drive, not a big job if you have access to a machine shop.
if you pull the front wheel and compare it with the 17 one you will see what I mean, you should be able to fit the rear at the same time.

 

On 09+ the speedometer uses a magnetic pickup, no gear drive.

 

quite right, but the unit is rotated by the wheel in much the same way as the old cable drive units were, it just a different size
