Frequently Asked Questions

Q: Does the "Big Bore" designation mean this pipe only fits big bore engine kits?
A: While designed to complement big bore performance, it is a race-spec component that works with standard 85cc setups to provide a more aggressive power profile favored by serious racers.

Q: Is this pipe easy to maintain?
A: Yes, the steel construction is durable. We recommend keeping it cleaned and lightly oiled if riding in wet conditions to prevent surface oxidation.

Expert Pro-Tip: On 85cc youth bikes, the exhaust mounting points take a lot of abuse. Always inspect your exhaust hangers and rubber grommets whenever you replace or remove your pipe. Worn mounts lead to pipe vibration, which causes cracks at the welds or premature thinning of the steel.
