I have one and use it. It works extremely well. Since it is for the rear wheel it does not require alot of pressure. I can still lock up the rear tire easily. It helps turn the bike in and also helps with rear wheel spin while exiting corners. Not sure about street application.

GARBAGE!! the only way to get a decent handbrake is to mount another caliper and run a front brake lever upside down.

can you go into detail about how to do this because i am interested in the same thing.

Well thanks for the advive darius, what about running the front brake M/C lever as a thumbbrake then run it to a dual foot master cylinder. then there is only one line to the rear caliper. i mean would there be anough preasure?

i had several models of gp thumb brakes.unfortunatly i am going to say they are garbage.i had to return 3 of them due to blowing out the pistons in them.also as well your thumb does not have as much strength of 4 fingers.so in short weld up a 2nd caiper and things will be al good.for anymore ??? on thumb brakes ask cbo he is the thumb brake specialist.

I got a much easier solution. Pizza pan that bitch. -2 + 25. Let off the throttle you got so much engine brake that ****'ll toss you right down. $100 bucks for new sprockets, no welding. no banjo fittings, no failed cylinders. Bango! done.

we use them and we love them----we used gsxr front master cylinders and flipped them upside down and mounted them on the left clip on. then we purchased the diverter from gptech along with a brake line. they work perfect. plenty of pressure

--but it isnt using your thumb, you press it like a front brake with 2 fingers

What is and were does "the diverter from gptech"go because i purchased a new foot mastercyleder from gp tech wich allows me to run both foot and thumb brakes though one caliper.
