## What it fits

The store lists a part under each bike or engine model it is meant for (the categories below) and may name models in the description. Do not assume it fits a bike or engine that is not named here; ask the store first.

- [TB Parts > ATC 70](https://tboltusa.com/store/tb-parts-atc-70-c-68_529.md)

Where a fitment line says "All", it means all years of the model named on that line, not all bikes.
