§ 02 / About this part
What it is
The PROX PISTON KIT FORGED 94.97MM C, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.
A forged 94.97mm piston for the 450 four-stroke platform, C-graded to match the bore letter stamped on your cylinder. Cross-references Yamaha part 5TJ-11631-00. Forged construction handles sustained high rpm better than cast, which matters on a 450 that lives near the limiter. The kit is complete: piston, rings, wrist pin and circlips, so one box covers the top-end rebuild. Measure your bore first. Piston-to-wall clearance decides whether the fresh top end lasts, and the grade letter on your cylinder tells you which size to order.
