This is the all new Racetorx thumb brake. Black only.

To those that are unsure what one is, this is a left thumb-operated rear brake, Thumb brakes are a great addition to any motorcycle. The thumb brake provides more control when braking so road, track, race and supermoto bikes will benefit when leaning into corners, Adventure bikes on technical routes and motocross all round.
Our kit is now on road bikes, track day bikes, BSB race bikes like David shoubridge Rich energy and Richard spencer, Dean Clewley in the National 1000cc Endurance championship and even AMCA's Tom Weston motocross competition bike. we are now pushing our kit into the adventure and motocross scene with great response.
We also do all versions of junction valves for the rear master cylinder so you can still keep your rear foot brake too.

In a thumb brake kit, you get the Racetorx thumb brake kit, a Brembo 13mm master cylinder and a reservoir kit.

Made from T6 billet aluminium, Hard anodised in black, Hardware including pivot pins and pushrods are made from Ti 6Al-4V Titanium with lockwire holes.

The thumbscrew provides a detent ball for precision and a 13mm Brembo master cylinder for reliability and perfect thumb pressure with the thumb lever providing a knurled finish for grip.

Handlebar fitment is the standard 22mm which 95% of bars are and in the coming months, other mounting options will come available.

This wonderful kit provides 4 points of movement to give the best position to suit you!

Comes complete with our GP reservoir tube kit with a black cap.

To complete the kit you can either go directly to your rear calliper or you can have the rear foot master cylinder in conjunction with our racetorx junction valves. You can order specific lengths of braided lines from either Venhill or Goodridge. If you decide to have the rear foot pedal usable in conjunction you'll need to fit a "Junction Valve" to your rear master cylinder which feeds into the reservoir port. This is a very simple layout and we are happy to assist where we can.
