Hi everyone. Hear me out on this one.


I am looking to "try out" a configuration of a motorbike that has the rear brakes and shifter position swapped. That is rear brake pedal operated with the left foot and the gear-shifter pedal with the right.


How hard/ impossible is it to...


1. Re-configure (the wirings etc) on any bike.


2. On a "complex" and high-end machine such as the V4?


For anyone interested, the motivation for this came to me when riding my new V4.


Unlike what most people think, my decade of training as an Olympic weightlifter, Yoga, Gymnastics, and consequently dealing with a lot of Physio,

has made me realize that the human body works in a unique way.

The left leg actually works in unison with the right hand/palm. And the right leg works in tandem with the left hand/palm.

(Hence "ideally" one ought to operate the clutch mechanism with their left-hand+right-leg combination. And the braking mechanism with their right-hand+ left-leg combination.)

Now I completely understand that 99.99% of riders have gotten used to what they have gotten used to (The body is also highly adaptable to what the rider is trying to accomplish) and I am not trying to prove or set a new way or anything,

I am just trying to see if such a "mod" is even possible?

I asked the dealer I purchased the machine from, and he gave me a expected+ polite "Get out of here" look/response.

But I will go distances for this one. I would not even mind "sacrificing" my brand new V4 to try it out.

Anyone?

Moving the rear brake over would be relatively easy. Would likely have to extend the wiring for the quickshifter. Hardest part would be figuring out how to actuate the shift linkage from the right side. I'm sure you could do something mechanical with enough engineering magic, but it would be tough. Maybe some kind of solution using an electric motor attached to the actual linkage and inputs sent via a sensor on the right side would be possible.

Would be a neat project, but I don't think you'd see any performance benefits. Hate to be a naysayer, but if it was more beneficial to do things that way, then MotoGP bikes would likely have that configuration.
 
Thank you for your response. I will keep digging.

" Hate to be a naysayer, but if it was more beneficial to do things that way, then MotoGP bikes would likely have that configuration."

^ I completely understand. Never too late to seek the truth. You never know, what impact a little, innocent curiosity can have

PS: There is some history to this.

Yeah, you can’t do that...

Ya need the go fast stuff (shifter n clutch) on the left side cuz that’s the emotional side of yer brain (where the anger is) (get mad at that motor) and you need the brakes on right logical side or you will brake late and wreck
 
There are specialists for handicapped people.
no problem for them, i think.
but i dont see the need.
i dont need the clutch because of a quickshifter and, imo, the left hand has always more feeling (for the brake) then any foot.

but mechanically interesting, i love the idea.

Ian Hutchinson (multiple Isle of Mann race winner) has a similar setup to what you're looking for, due to a motorcycle accident damaging his left leg.

He raced in BSB Superstock 1000 when healed, maybe for Tyco BMW. The Tyco team is based in Northern Ireland. Perhaps if you contacted the race team, they may be able to enlighten you? He may have used a thumb rear brake though.

You could buy an old Harley or Brit bike and check it out, otherwise its not happening. I also think your theory is deeply flawed
 
Further to my previous comment, ive owned many right hand and left hand shifters at the same time and never felt any difference despite going between them regularly. It's like going between gp and std shift, you just develop a preference (gp shift is better though!)
 
How many amps would a 12v shifter have to pull to equal the force of a air shifter? (And how much would it have to weigh?)

And how many times avg does that Yamaha get shifted per race?

It seems like it would kill the battery on a race bike. Don’t they have little or no charging system???

Ha ha ha ha.

If you want to try your theory it’s possible for sure. I’m not in love with a mechanical linkage running to the other side in a performance situation for the shifter. I like this electronic idea the best. That shouldn’t be too crazy except finding where it all fits. I’d guess all this will be an experiment until you find what works best for you. May take a few tries. Some MotoGP riders use Rear thumb brakes, so obviously you could put that wherever you want.

lets say sensor force is nearly shifting force = 10kg
three times is 30 at the lever.
a cheap universal door lock motor is rated 5kg and draws 2A. and is fast.
so...15A/1second is 0.0042AH per shift.
damn, where to put these 6 motors

Mate all you need is quickshifter and a thumb brake

Going to cost you 1k at max
