I have to put a New track on my 800 Twin and wondered what was the best size to go with. 121x15x1" or 121x15x1.25" or 121x15x1.375" . I do alot of Trail Riding, Groomed and some Not and an occasional trip on the River.Any Advice would be Apreciated. and also need a Track. Thanks ZR.

It depnds what you want. If you want the most top speed, go with the 1", and itll hook good, but still have the top end. The other two will hook like crazy even w/o studs and you may lose 3-4 mph on top. The F7 snopro with 1.375 hooks like nothing ive ever seen, but it will lose to a standard F7 on a lake race. Id go with the 1.25, as an all around track, because the 1.375 can be a little long at times and you risk tearing lugs if your not in a lot of snow

i agree with catkid 100%, for what that is worth, maybe just one more opinion. 1.25 best all around length for me. :D

Thanks Guys, I guess it is a 1.25". Now if I can Find one in a Camoplast Predator??? Thanks. ZR

If your not studding go with the 1.25" [9818], you'll only lose a couple of mph's up top, but if your going to stud stay with the 1" [9830]. Once you start to add studs to the 1.25 track it will really start's to take some mph's away from you, but if that mean's nothing to you then go with the 1.25 all the way. Great trail runner.
