For the 2021/2022 season all BackwoodsBMP rear bumpers will venture past this “breakpoint”. Our focus is again to divert and disperse energy throughout the snowmobile, transforming what would be an unfavorable situation, into a progressive result.

By reaching past this “break/bend/snap/crash point”, energy is now able to effectively communicate amongst components to further dissipate and disperse, where before there would be no choice but to unleash the full potential where previous bumpers cease to exist.


The all new Gen4 rear bumper is a force to be reconded with. By taking into consideration the forces and strains that go into everyday riding we have designed a bumper that targets the true problem areas of our machines design.

-Built to transfer eneergy throughout snomwobile

-All New 3 peice design to ensure performance and protection. 

-All mounting hardware includded
