The Yamaha Grizzly 600 was the first installment to the Grizzly family. We took full advantage of the air cooled, 4-stroke engine with an 8% increase in horse power over stock. With the Penland Pro Series installed, we were able to see gains in the bottom end torque for cross country riders.

Each HMF Exhaust:
Whenever you add an after-market exhaust system to your machine, tuning your carburetor is, in most cases, an absolute necessity. The proper jets and EFI settings are extremely important for the performance and lifespan of your machine. Tuning Kits
are available to ensure your machine runs at it's top performance and your HMF Warranty remains valid.
