Honestly I've rode both the R models and the S models. S handled better and are lighter. Power is a mute point. Be happy to make a sweet deal on some s models. Lol One had a bitubo rear shock a D&D pipe and a Yosh pipe. Have 1 roller and 2 with motors in pieces and 3 bikes total . Steven
Huh? Ridden the same there is no advantage to the smaller bike. Some riders may be able to go faster on them but that's the rider not the bike.
What's up Lance?????!!!!!!!! Great to read that you'll be out running this year. You still have the ZX7/9?
Just seeing this, I'm going to try and get out for a couple races. Not sure on what. The zx7/9 sold a few years ago. I didn't want it just setting collecting dust.
