- 2 Piston ring sets
The advantages of this kit over other big bore kits:
- Lightweight pistons with short pin
- Bare piston weight is 333 grams
- Total piston weight with pin, locks and rings is 433 grams
- Correct compression ratio for the street (10.5:1)
- Good value compared to the higher-end kits
This Razzo Rosso piston kit was carefully developed to fill the gap between lower-cost old technology piston kits and some of the higher cost European piston kits. Combining the Euro-design features with made-in-America quality, these Razzo Rosso pistons provide Dyno developed maximum performance for the street, at a reasonable price.
In the dyno graph below, The Razzo Rosso piston kit was used in a stock 900SS with only mild intake porting done to it. It was tuned with a PCIII for the correct air-fuel ratio. The exhaust was a Termignoni CF muffler only system with standard headers.
The torque number was a direct result of the bigger bore (944cc) and higher compression ratio. Your results may vary.
