Descripción

The Warp 9 front sprocket for the Altis Sigma is cut from hardened tool steel for 428 pitch chain. Each one comes with a new jackshaft seal already installed in the sprocket. Choose the stock 13 tooth or the 14 tooth.

Fitment:

  • Altis Sigma

NOTE: 428 chain pitch only, not for 520 pitch drivetrains

The countershaft gear is the smallest one in the drivetrain, so each tooth meets the chain more often than anything out back. Warp 9 answers that with tool steel and a black oxide coating, a combination the maker chose for longevity.

Warp 9 also made the flange larger to reduce movement on the driveshaft, so the gear sits steadier under load. Because the seal arrives fitted, one swap renews two wear items on an electric dirt bike that sees real trail miles.

Gearing is the other reason to open this up. The 13 tooth keeps the OEM ratio. Warp 9 says the 14 tooth adds top speed and extends range by lowering motor rpm, and that the trade is less torque.
