I am wondering what gears to run on a 21 expert turbo?
It will have a dj (ibackshift) clutch kit and a Maptun tune.
I believe the sleds come stock with 21t top 53t bottom but correct me
If I’m wrong

Thanks

i've switched the top sprocket to a 19T on all 3 of the Freeride 165's I've owned with the last two being turbos. all of them had ibackshift clutch kits.

21/53 = 102KMH track speeds at 1-1 shift. If your running a 154 or 165 this is the ideal ratio if your running a tune or close to the Gen5 HP level.
19/53 = 92 KMH track speed at 1-1 shift. This is too low for a 154 or 165. Would work with a 175 tho.

I would keep the stock gearing (21/53) for typical riding. Gear down/up if you have a unique riding condition, i.e. a lot of trail, towing a toboggan, etc.

Shouldnt need to gear down if the tune is making more power.

Id just leave gearing stock and watch your tach. If rpm are where they should be. Gtg
