Description
The CP Carrillo M4049 forged piston kit is tailored for 2009 2012 Kawasaki Ultra 260X and similar 1498cc engines using 83mm standard bore and 69.2mm stroke. With a 9.5 to 1 compression ratio, this kit delivers stronger midrange torque and throttle response compared to lower compression turbo pistons. It maintains stock displacement while upgrading the critical piston assembly to forged construction that handles high rpm and boosted loads far better than OEM cast parts.
Each M4049 piston is designed to work with rod 5403, 827 2250 18CP3C wrist pin, 827×063 SWL locks, and CPN 3268 ring set. The forged design emphasizes precise ring grooves, stable skirt loading, and a crown profile that supports efficient combustion under performance conditions. This makes the kit ideal for Kawasaki Ultra owners who tune for more power through ECU flashes, intake upgrades, or forced induction.
- Fitment 2009 2012 Kawasaki Ultra 260X and similar 1498cc engines with 83mm standard bore.
- Compression ratio 9.5 to 1 for improved acceleration and midrange power in tuned applications.
- Forged piston strength significantly exceeds stock cast components for high performance use.
- Paired with 5403 rod, 827 2250 18CP3C pin, 827×063 SWL locks, and CPN 3268 rings for reliability.
- Optimized ring seal and combustion chamber design promote consistent power and cleaner running.
- Excellent upgrade for recreational Kawasaki Ultras seeing ECU tuning, exhaust mods, and harder riding.
For Kawasaki Ultra 260X owners wanting a forged piston upgrade that adds compression and strength without changing bore size, the CP Carrillo M4049 kit is perfect. It transforms stock power into responsive performance while building a stronger foundation for future modifications.
