Got my first crank from Mrrpm cycle. The new cheaper ones for the 800cc based engines.
Kits include, crankshaft, 2 rods, and rid bearings. Even has the keyway for the flywheel to align properly!!.

I took the time to measure up the journals... Gotta say, there machined quite well! All specs are at the maxinum of the "new" specs from the brp service manual.

The rods are pin'd and machined, the aren't fractured like the stockers. So if they prove to stand up, you will be able to machine em down again! If you rebuild again.

I do however highly recommend you loosen and re-torque the rod bolts before installation according to brp specs.

I overhauled a stocker 650 for a guy with this new crankshaft. He lives a few hours from here and did the install himself, just talked to him, got er all fired up and sounds great!. Yet Another happy customer from r1p/ Mrrpm!!!
