Default 2018 XCR 800 SB Gearing

New to me sled with the cobra track and 162 studs. I have it completely apart to make some repairs and figured I may as well look into a gearing change while I am sorting things out.

I am looking for corner-to-corner speed, but don’t want to lose all top end. I know this means gearing it down, but am curious what folks found for a sweet spot. This is not my primary sled, so I am not looking to get big bucks into clutching/gearing.

Suggestions?

Thanks

22/38 a 1.73 ratio. we have tested this to death. in almost every case we gained a bit of top end. and the corner to corner was way better. 2-3 length improvement in 1000'

I have the kit from Rick that includes the gear change as well as the clutching change. Ill just say it is an absolute rocket corner to corner. Extremely pleased with the increased performance it gave.

Thanks. I will likely just drop in the 38T gear and call it a day. I won’t be on the sled a ton, so I want it to be fun to ride but don’t need to sink a ton into clutching.

You won't regret NSP kit with gearing.

I’ve heard nothing but good things. This will primarily be ridden by my girlfriend so I want it to be fun, but I also need it on the trail!

Agreed, heard real good things on Ricks kits. Ive played around with setups but I cant help myself as I like to mess with Stuff. An easy solution if you dont want to play around would be to get the NSP kit. For gearing either use 22/38 as suggested or 23/40 the 23/40 needs a 70P chain (1.74)
