A.P.E Street Performer 128ci Big Bore Package

Description

Over the past 5 years, we’ve offered 4 different M8 Big Bore bolt-on packages (Stump Puller, Tomahawk, High-Output, Silverback). We continually strive to learn, improve and develop, and our latest combo has reset the benchmarks.

Smooth and broad power delivery, strong low end torque, valve train friendly, happily runs on pump fuel and capable of 150+ Horsepower & torque. This combo is an absolute blast to ride!
