  • Yamaha Zuma 50 2t Stage 2 Performance Kit

    Ready to take your Zuma 50 2-stroke to the next level? This is the Stage 2 performance kit that will take your Zuma performance up a serious notch over our Stage 1 Kit. 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 7000-12000 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 setup doesn't want your engine screaming like that, so you've got to switch it up to make higher revs.  Add in the NCY big bore kit, and your bike's horse power will increase 135%.  Don't believe us?  Check out the dyno for some truth serum. 

    Remember that performance parts do not come with any warranty, and will void your factory warranty. Follow good break-in procedures, and work with an experienced tuner for best results.
