Description
Reduce backpressure and improve exhaust flow on your Kawasaki 1500SXR, 15F, or Ultra LX with the R&D Waterbox Bypass Kit. This kit reroutes cooling water to minimize restriction in the waterbox, boosting throttle response, reducing heat soak, and helping maintain higher top speeds longer.
Flow & Performance Benefits
- Bypasses excess water from waterbox to lower restriction
- Improves exhaust scavenging and reduces backpressure
- Adds noticeable throttle crispness and acceleration
- Keeps engine temps lower during extended runs
Stock waterbox routing on these models can create unnecessary drag. Bypassing optimizes flow, giving you a freer-revving engine and less fade – especially valuable on modified or race-prepped SXR/Ultra LX skis.
Simple & Effective
R&D provides all necessary hoses, fittings, and instructions for a clean install that doesn’t compromise cooling safety.
- Maintains adequate waterbox/exhaust cooling
- Easy bolt-on with minimal tools
- Popular on high-horsepower Kawasaki builds
- Helps sustain top-end speed in rough water
Feel the extra snap and sustained pull.
Install Overview
Reroute select water lines per diagram, secure clamps, test for leaks. Monitor exhaust temps initially. May pair with cooling upgrades for full effect.
Unlock better flow and response on your Kawasaki with the R&D Waterbox Bypass Kit.
