If you're restoring a classic British bike, it's the little parts that count.

This is a brand new rear brake lever spring for a wide range of BSA and Triumph models.

It fits the T120, TR6, T140, TR7, T150, Bonneville, Tiger, and A65.

The part numbers cross to 37-4049 and W4049.

This spring provides the return tension for your rear brake lever, making sure it snaps back properly after braking.

It's a genuine Triumph brand part.

If your brake pedal feels floppy or the spring is missing or rusty, this is the exact replacement.
A small but essential piece for any vintage British motorcycle project.
Keep it original.
