Driveline, Yamaha Banshee RZ 350 diecast Crankcase, Part# 91-5733

Description

These are our new die cast Driveline Banshee cases that we have been developing for the last 5 years. We have made a lot of changes to the OEM design while still retaining the stock look. We have added extra material in all the places the stock cases were lacking for today’s larger stroke cranks and aftermarket cylinders. You can trench these cases up to a 14mm stroke without any epoxy or welding. The top case can be bored and machined to fit a DM cylinder and not break through on the sides of the transfers.

This set of engine cases are pre-trenched and will fit a 7mill or a 10mill crankshaft. The sealing area is much more on these cases because of the extra material we have added compared to stock cases that have been trenched for a 7mill or 10mill crank.

The following items are included with every case set:
