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
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.
