Wondering what to put on my stock 850 xp. I hear any bigger u should use a Clutha kit. Also if I was goin with a clutcth kit which one and if there hard to install. My neighbor is all around machanic wit most everything ski doos ect i wouldn't mind a kit for her almost to stock for me aha thx fr any input

 

I think the tire size depends on most of want type of riding you do. The 30's are great in mud and slow speed stuff, but if your more into higher speed trail riding I would go with the 28's. Your 850 has the power to turn them both. The bigger you go the more strain you put on your drive line for longivity.

Either way EPI has a kit that would improve your machines performance all around. If you use the 28's ans do higher speed riding go with the Sport Utility kit for 27-28" tires. If your main riding is mud riding then use the EPI mudder kit for either size. You can check them out more at www.epiperformance.com

 

Yea I'd say 28s becuase I won't be just strickly mud even tho I will be in it abit. Alot trails also and 28 s still should keep abit of quickness with sport utility clucth kit
