Good To Know

Q: Will this piston kit fit my Honda TRX90? A: Yes, it is designed specifically for the TRX90 Sportrax 90 from 1993-2025, but always verify your engine's current bore condition and serial number before ordering.

Q: Do I need to rebore my cylinder to use this piston? A: This is a .020 oversize piston, so your cylinder must be machined to the corresponding oversize to ensure proper clearance.
