I just scored a pair
of used Talon
/Excel 17 inch wheels at a good price for my YZ450F supermoto which will be run in speed hill climbs next season. A spare set so that my lad can switch between cut slicks and wets. Problem being that the front hub is for a WR with the notches for a speedo drive. The rear fits perfectly (it already had Talon/Excel wheels) but naturally I have no speedo drive. I was hoping to just fit an oil seal and use the collar from the YZ but though the axle and spacer and bearings are identical the collar isn't long enough. I'll give Talon a ring as both hubs are made by them as the collar on the YZ doesn't look like the standard Yamaha
item anyway (it is tapered on the fork end) and the WR wheel
came with a stepped collar on the speedo side which doesn't seem to be used with a Yamaha
hub. The brake side is perfect for alignment. Buying a speedo drive to sort it out (left unconnected) is not an option at Yamaha UK prices £104! Using both collars might work but with the WR one next to the fork and the YZ one against the bearing it seems to bind up. I'll try them the other way round tomorrow but has anyone run a WR wheel in a YZ without a speedo drive and how? If all else fails I know someone that can turn me up a custom collar if I can provide the dimensions,
Mind you I can't see us swapping the front wheel very often as most people run a wet on the front even in the dry for the sub mile start to finish courses we run. The lad likes the WR excel
wheels though because they have fancy blue rims. The bike has a huge ABE front disk rotor and I couldn't get the wheel out without unshipping the caliper from the fork *and* the rotor from the wheel. Not enough clerance between the rotor and rim to get the caliper free - unless I'm missing something. I won't want to be doing that in the paddock in a hurry as the rain starts.
