I need to get my son’s bike ready for road racing, which for his stock class basically means change the tires. The stock wheels are currently mounted with knobby tires, which are prohibited. I’m lost and need some guidance.
Can I use the stock wheels? When I looked at Dunlop 10” tires they were intended for tubeless use and the spoked wheels currently use tubes. Can I use the stock wheels as a means of cost control? Are there any adverse reactions from using the stock wheels? I haven’t yet verified with the rule book which wheels are mandated but I do recall that OEM bearings must be used, so that leads me to believe I have to retain the stock wheels...UNLESS Honda has another OE wheel available for the bike. Whew!
I found this for another brand that at least sheds light (maybe) on tire size, though I saw another reference in my online search for 12” tires.
SuperMoto Mini Race Tire by Shinko SR560
High quality 10" tires for the Honda XR /CRF50 / Yamaha TTR50 and Suzuki DRZ70.
Great for riding the SuperMoto track, Kart track or your driveway race track. Works well on cement or pavement.
Front and rear tire is 80/90x10 which is like a (2.75) size.
We recommend 2 of the 80/90 (2.75) tires for stock swingarms. However the 90x90x10 (3.00) rear tire should fit in most.
The above quote opens the door to questions on using dissimilar widths, not sure the impact on rideabiliity using dissimilar widths (another issue).
In summary my questions are
1- What range of tire sizes can I spoon onto the bike
2- What wheel options are there
3- Pros Cons of tube vs tubeless
4- Pros Cons of using dissimilar width tires
Hopefully someone can help me with this while I take another look at the rule book.
After market aluminum wheels are allowed but must retain stock 10" wheel size and OEM style hubs.
This removes the question about using 12" wheels. Also says that we may
change the wheels, but not that we must. I came across a set that were nearly $500. We're not at that level and it's his first season. I'm trying to do this for just a little over transportation and motorcycle operating costs.
