The handlebar fitment is standard 22mm, which fits most bars. This kit offers four points of movement to provide the best position to suit your needs. The GP reservoir tube kit comes in black and is included in the package. You can choose to connect directly to your rear calliper or use the rear foot master cylinder in conjunction.

MASTER CYLINDERS-
  • 11mm Master cylinder for single cylinder 125cc-500cc motorcycles (supermoto, motocross, trails & road)
  • 13mm Master cylinder for 2, 3 & 4 cylinder 500cc - 1400cc motorcycles (Road, track, superbike and adventure)

The Racetorx Thumb Brake has additional thumb paddles for personal preference, This is listed in the drop-down menu. You can also purchase the paddles separately here - http://racetorx.co.uk/product/rtx302/

When wearing a road/race boot or a motocross boot, it's difficult to gauge the pressure you're applying. However, if you use your thumb to apply pressure through the paddle, you can achieve more control while breaking in a corner on a race track, controlling the angle of the bike while airborne on a motocross track, navigating a technical route on a trails bike, and even controlling wheelies on a stunt bike.

A lot of people ask What is a thumb Brake?

 
It’s a left thumb-operated rear brake, Thumb brakes are a great addition to any motorcycle, especially on a race track. The thumb brake provides more control simultaneously when braking and leaning into corners. They are also great to help with wheelie control and stunt riding.
Thumb brakes are great additions for any motorcycle from a 300bhp MotoGP bike to a 50bhp 450cc Supermoto or a Motorcross bike and trails for technical routes.
The Australian 500cc world champion legend “Michael Doohan“ was the start of the thumb brake when he seriously injured his right leg so switched to a handlebar-mounted thumb-operated brake. Doohan then in the 90’s won several championship races with the use of the thumb brake, It has been a benefit ever since, other racers noticed the benefits of the thumb brake and now it's one of the most used aftermarket rear braking kits on the market.
Some questions that are commonly asked-
Q: Can you run in-line with ABS?
A: Yes, you can keep the ABS intact
Q: Can you run directly to your rear caliper?
A: Yes, you can remove the foot brake pedal and master cylinder completely and feed a new braided brake line direct from the thumb brake master cylinder to the rear caliper.
Q: Can you run the thumb brake in line with the rear foot pedal?
A: Yes you can, the rear master cylinder would require a Racetorx junction valve " http://racetorx.co.uk/product/rtx450 ", there are only 5 variants to suit the master cylinder you have, here is a link to the Racetorx junction valves http://racetorx.co.uk/product/rtx450 these are quite universal to Brembo, Nissin and non branded units.
Q: How do you build the kit?
A1: If you want to fit the Thumb brake direct to the caliper, (NON-ABS models) Remove the rear foot brake pedal and master cylinder and remove the braided line (be sure to keep the brake fluid clear from the bike as much as possible, also when removing the surplus parts clean any residue spilled)
Fit the thumb brake and feed a pipe or cable up to 10mm thick in the routing location you want, this would be from the thumb brake master cylinder port down to the rear caliper routing under the top yoke, under the tank and down the right side of the bike. This is so you can work out the length of braided line you require.
A2: If you want to fit the thumb brake in conjunction with your rear foot brake, (This includes ABS models) Remove the reservoir on your foot master cylinder, some will be a screw-in adapter, some with a teardrop adapter with a small M4 bolt, others will be a plastic adapter pressed into a donut-like rubber, these just pull out with a good tug and wiggle (don’t be shy). Clean brake fluid that will spill out and in the area the junction valve locates, then fit the correct “junction valve” to suit the master cylinder. Racetorx so far does the Cylinder type that screws into the built-in reservoir and the Teardrop type.

Bike Fitment-

These are a universal kit for the majority of motorcycles, Road bikes, race bikes, adventure bikes and even motocross bikes.

We have the most adjustable thumb brake on the market and even then our kit on some bikes can touch fairings, tanks or frames, This being said with the adjustability you can work around it nicely most of the time.

Motorcycles with Handle bars have the most clearance whereas if using clip-ons you can have some challenges, the Ducati V4 Penagale has no room and the fairing would need some modding, Ducati V2 Penagale is similar with more clearance but still touches at full lock.

Adventure bikes. motocross bikes and streetfighter bikes all have clearance.

The list would be endless but to give some idea of bike styles which our kits are fitted to so far-

  • Ducati V2 & Ducati V4 (moto Rapido) BSB
  • CBR1000 (Michael Dunlop) IOM TT
  • Kawasaki ZX6 (Michael dunlop) IOM TT
  • Triumph 765 (Bathams racing)
  • GSXR 1000 (Team classic suzuki)
  • Kawasaki zx10 (FS3 BSB)
  • Aprilia RS660
  • KTM super duke 1290 & 1390
  • Yamaha Tenere 700 & World raid
  • Yamaha MT10
  • Yamaha YZF 250
  • Yamaha YZF450 & WR450
  • KTM 690 SMCR
  • KTM250 2 stroke
  • KTM 300 EXC
  • Yamaha R1M
  • BMW M1000 (Tas BMW BSB)
  • Honda CRF450
  • Honda SP2

Again this is not a list of the bikes they will only fit but a list of bikes that our kits are fitted to plus many more.

The Latest BSB Thumb paddles are now available. working with the team's Moto Rapido, FS3, Hawke we now have 2 new thumb paddles that are suited to the BSB riders.

7 reviews for Racetorx Thumb brake - Bred to race

  1. Clive

    Had one fitted on my ktm exc f500 by Torque racing near royston Hertfordshire
    Great bit of kit but wondering if one can get parts ie thumb lever if it brakes out on the trail

  2. Moto Rapido Ducati (verified owner)

    We love this product, it is so versatile with different models and peoples thumb position that it makes it the number one product for any road rider, track or racer.

  3. FS3 Racing

    Here at FS3 Racing, we have been working closely with Racetorx testing and developing the thumb brake on our superbikes.
    The support and turnaround on parts we have suggested has been second to none!
    The quality it brilliant, the look and design is amazing and it works perfectly lap after lap.
    Couldn’t recommend highly enough.

  4. Andy Baker (verified owner)

    I track day SuperMoto on a YZ450F and always use the rear brake as an afterthought. Spoke to Dale at Racetorx and he fed me all the information on the thumb brake they designed. The quality is very high, every part is a precision fit and paired to the Brembo master cylinder. I chose the option to keep the rear foot brake and bought the junction valve, everything synced perfectly. This is a quality piece of kit and it looks the business. Racetorx tell me they are designing a crash cage to protect your investment on those low side wipe outs, I will definitely be purchasing one.

  5. Dean Clewley

    We, Team DMR Kawasaki have been working closely with Racetorx to maximise the design and function of their Thumb brake with competing in the National Endurance series on board our ZX10R.
    Our feedback is rather simple…. by far the best thumb brake product we have ever used. The force generated is superior to any other and the adjustability to suit any riders mounting position is sublime whilst the product finish and quality is outstanding.

    its a must buy Product over any other competitor !

    We also use this in conjunction with the junction valve meaning we have the thumb and foot operated brakes at the same time

  6. Stuart Eckersley

    Fitted the thumb brake to my Tuono V twin as I don’t have a lower right leg. Easy to fit and very impressed with the quality although not cheap. Looking to maybe purchase another to fit to my Triumph Scrambler after I’ve run this one for a little while.

  7. Steve Ellis (verified owner)

    I wanted a Thumb Brake System because I can only partially use my right leg, and certainly not the foot Brake.
    I’ve retrofitted Brembo Calipers/Discs/MC’s so was happy to find the RaceTorx product with a decent size Brembo Piston.
    Also important was the drop below handlebars to miss the horrible massive KTM plastic Switch-Gear, which this does admirably well. Also affords some useful further adjustment options.
    Last but not least it’s really nice quality material and finish..nothing scrappy or cheap.
    Helpful phone convo pre-purchase, and arrived quickly and well packaged/presented. Even included some extras and a sachet of harribos!
    Most important of all it works well, and gives me a rear brake again!
    More than happy to sing praises and recommend this product))
