Ready to take your Zuma 50 2-stroke to the next level? This performance kit will take your Zuma up a serious notch! Save $$ by purchasing this entire kit.
This exhaust has a race-tuned expansion chamber to help your engine make maximum power in the range of 4000-12000 RPM. The included variator parts are necessary modifications to help your engine rev that high and take advantage of the power available to it. Your stock variator can't handle that kind of power so you've got to switch it up to make higher revs. Add in the NCY 72cc big bore kit, and your bike's horse power will increase by roughly 4-5 horsepower!
Follow good break-in procedures, and work with an experienced tuner for best results.
