I'm looking for some general knowledge on this... If I put a 15"x121"x1.75" or 15"x121"x2" track under my FX Nytro (standard), what kind of top end speed loss do you think I will be looking at?
I'm thinking 5-10mph, but that's basically guessing on my part.
Thanks for the info,
Will

Well, this is my experiance, little different. :
121x1.25= 105
144x1.75= 92
This is on the speedo with no gear or clutch changes.

just got done reinstalling a 1.75 polaris snowcross track. The track would rub the top tunnel protectors so I notched track 3/8 " worked good but lost 8mph compared to buds rtx 94mph to my 86 mph. I now have 8tooth drivers in with 23 top gear and a ulmer clutch kit. The drivers will help with top end loss as the track would still rub when at top speed from ballooning. Will know after this weekend how it goes.
