§ 02 / About this part
What it is
The PROX PISTON KIT ALUMINUM 47.45MM B, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.
B-grade sizing at 47.45mm for the CR 85 top end. Honda's plated cylinders wear in fractions of a millimetre, so ProX grade these pistons in steps; measure your bore with a dial gauge and match the letter to the barrel rather than guessing. Kit includes piston, rings, pin and circlips. An 85 two-stroke lives at the top of the rev range every session and eats top ends quickly, so most race bikes see a fresh piston well inside 40 hours. Check ring end gap in the bore before assembly and it goes back together like stock.
