The Triumph Speed 400 motorcycle chain tensioner fit for your bike is a must-have accessory to ensure safe and smooth operation of your throttle. This kit includes 3 essential components: a throttle spacer, gear shift, and throttle spacer. The throttle spacer, a lightweight and durable spacer, provides a smooth and gentle flow of air to the carburetor, maintaining optimal fuel-air mixture. The gear shift allows for a clean and uncluttered view of your shift pattern, reducing shift and pedal noise. The throttle spacer, when paired with the throttle spacer, works together to provide a perfect adjustment for your throttle, reducing wear and tear on the engine and ensuring optimal performance. Trustworthy and easy to install, this set is engineered to provide you with a stress-free riding experience, even in wet and dusty conditions.
