   Running my Ninja 300 next week at Summit. It will be the first time on the bike at SP, so not familiar on the proper final drive ratio.
   
   Thanks for any advice you can give!

   On our rc390 we topped out around 110-114 depending on draft with 42whp. I'm not sure if that helps but I'd assume you'll end up around the same speed.
