BBR Motorsports 132cc Big Bore Kit – Honda CRF110F |2013-2026|

BBR Motorsports 132cc Big Bore Kit – Honda CRF110F (2013-2026)

Unlock the true potential of your pit bike with the BBR Motorsports 132cc Big Bore Kit. This is the largest bore kit available for the Honda CRF110F that offers a 100% "bolt-on" installation, meaning you can achieve massive power gains without the need to bore your engine cases for cylinder sleeve clearance.

Professional Race Performance

Designed for riders who want more torque and better pull through the gears, this kit transforms the CRF110F from a mild-mannered play bike into a high-performance race machine. The 55mm lightweight aluminum piston increases compression to 10.25:1, providing a crisp throttle response and a significant boost in horsepower across the entire powerband.

Engineered for Longevity

BBR uses a high-quality aluminum cylinder with a steel sleeve to ensure optimal heat dissipation and long-term durability. The kit is fully compatible with 2013–2018 carbureted models and 2019–2026 EFI models, featuring a dedicated port for the EFI temperature sensor.

Installation & Tuning Notes:

To get the most out of your 132cc kit, we recommend the following supporting mods:

• EFI Models (2019+): A fuel controller or ECU reflash (like CJR) is mandatory to prevent lean conditions and ensure engine safety.
• Carbureted Models (2013-2018): Re-jetting of the stock carb or upgrading to a larger 26mm carburetor is highly recommended.
• Pro Tip: Pair this with a BBR High-Performance Camshaft and an aftermarket exhaust for the ultimate "Stock-Mod" build.
