## 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.

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

## Description (the store's own text)

Upgrade your KLX110 with the TBparts 110cc Bore Kit, featuring a 53mm high compression forged piston for maximum strength and performance. This kit is designed as a drop-in upgrade for the stock cylinder head—no case boring required! The forged piston offers superior durability under high RPM and heat conditions, making it perfect for aggressive riders or racers.

**Key Features:**

- Forged 53mm piston – built for strength, power, and longevity
- High compression for improved throttle response and low-end torque
- Works with the stock KLX110 cylinder head
- Drop-in installation – no machining or case boring required
- Ideal for stock 110cc engines and compatible with most performance upgrades
- 12.2: compression ratio

**Kit Includes:**

- TBW1759 - High compression forged piston
- TBW0818 - Stock bore top end gasket set
- TBW1954 - Aluminum cylinder

**Application:**

- KLX110 - 2003-2009 (Requires TBW0305 LH gasket)
- KLX110 - 2010-Present
- KLX110L - 2010-Present
- Suzuki DRZ110 - All years

**Note:** Requires high-quality fuel (91+ octane recommended). Avoid stale fuel, as octane loss can lead to detonation with high compression setups.
