has anyone put a thumb brake on their xs650 or another bike ,intrested in both cable and hyd versions as have both types of bikes , due to foot / leg problems reconcidering the idea after a near miss with a idiot driver ,takes to long with present set up in a emergency ( have to lift foot and move it forward and then press down ) all the commercial set ups are very $$$
 
Hi Flea,
us Canadians mostly see thumb controls on snowmobiles because thumb controls are about all you can operate when wearing down-filled bag mitts.
But to put one on a bike without spending the big bucks?
Think about moving the rear brake operation to the clutch lever and operating the clutch with your foot via a homebuilt linkage.
My thinking is that you sometimes need to brake right effin' quick while clutch operation can mostly be delayed to suit your limited foot movement.
 
mmmm..its an idea but don't think I would have enough control over the clutch but that's a thought and look into snowmobile controls... what sort of braking do they have (or do you just scream loudly all the way down the mts :yikes: )

Hi Flea,
no, that's the snowboarders, most snowmobiles have a hydraulic disk brake in the transmission.
 
Given the cost of thumb brakes I would have though you would have done better to invest in improving the performance of the front brake?
Due to an arthritic condition I'm unable to operate my back brake and have not encountered any issues just using the front.
 
plus 1 with really good front brakes a rear is redundant. Heck I gotta watch downshifts skidding the rear when I'm on the front brake hard.
 
Do you have a rear disc? If so, how about a valve and having the front brake lever control both wheels.
You would need to incorporate a load apportioning valve as well.
Both Motorola Guzzi and Honda have used linked front and rear so there may be something there you could adapt if the idea appeal.
 
running twin discs on the front now , also on the xs650 have put a longer and bent slightly up xs 750 pedal , have also been looking for the guzzi system on and off for yrs but due to the small amount of guzzies in oz (will have to look into Honda , any ideas which models ?) and over seas their still like rocking horse shit ,the trike builders seem to love them .. looked also at k levers (put out by klicktronic ) but in oz money about $2000.... the front brakes are great just the reaction times in a sudden stop / emergency stop to move the foot / leg to the brake pedal is dangerious (scared both me and a idiot driver shitless recently ), tried forward controls (this is all to both a weak leg and foot ) and they suit better but too tiring a position on the leg very quickly , hence now looking at thumb brakes..want to put on the xs650 (drum) and the tdm850 (disc ) so cost will be importent .. tried looking on the bike riders disability sites but most seem to be pushing the flash $$$ systems... any ideas would be great
 
hi a friend of mine, who lost his left leg uses a front master cylinder turned round on to the left side of the bars and a shorty lever facing him so he can pull clutch and break [ using left thumb ] all at the same time . worked for him for twenty years riding road and track
 
...will have to look into Honda , any ideas which models ?
.... the front brakes are great just the reaction times in a sudden stop / emergency stop to move the foot / leg to the brake pedal is dangerous

Have a look at this and this and this and this which gives some information. Note the comment about some countries requiring two independent braking systems. You would need to see what your local requirements are.
Also linked systems (as far as I can recall) use the foot brake to apply the rear and one of the front calipers and the handlebar leaver is used to apply the other. Whilst this satisfies legal requirements of two separate systems I don't think this will be of any benefit to you.

I also suggest that you practice just using the front; once you get used to it you get allo of the stopping power you need of if you haven't consider a brake upgrade.

Also, without wishing to state the bleedin' obvious, if you keep getting intop situations where you need to make emergency stops perhaps you could try anticipating what other road users may do or better still, assume they are all out to kill you and ride more defensively.
No insult or criticism intended. :cautious:
 
thanks been riding for many many yrs and now older ride defensively BUT as you said their out to kill us so try as we like there is always something that can crop up ,idiot drivers , cows on a blind corner , kangaroos that aim , just that last brush with a idiot driver made me realise I needed to do something a bit better with the brakes than what iv been riding with the last couple of yrs ( also in mt country so steep dirt drive way /rds , where back brake saves the front end washing out ) , hence thinking of the thumb brake BUT had another look at the interagrated brakes to find there is a difference between intergrated and abs, both using the proporsioning valve BUT only the intergrated would work for my needs/ or any one else in my position ie. front lever operating both 60% front and 40% back , with the back also only operating via foot pedal , so have to chase up the older model pre abs bikes.. thanks those link are also great as the more info can get first will make it easier
 
a bloke I know with a missing left arm has done similer on the right hand side ie, front brake and hyd clutch mastercyds and levers (plus thumb accelerator ) ,and works ok for him , but iv a hyd clutch so seting up a back brake there would definitely work but looks incredibly messy ,and after all the work put into the bike would like a system that will look neat as well (bike rider your name is vainity..or some such miss quote ) actually that's where the k levers coming into their own , the 2 levers / systems share a common m/cyd with 1 long lever and 1 short lever which then can be used in various combinations clutch/ brake.. brake/ brake etc looks good but incredible price ,same as a lot of health / accident items aimed at insurance companys and gov subserties ,ever noticed what should be a $50 shower chair (in the real world ) cost 2-300.. but the health / insurance industry is a rant for another time and place
