UK is front rhs, I think the rest of the world is the other way round.
TBH, your probably right handed, and therefore probably stronger grip from all that w@nking you did as a kid. That means you can probably better modualte your braking with your right hand. As over 70% of braking (its physics) happens on the front wheel, due to all the weight being thrown forward and onto the rim through the front brake, it makes sense that the hand that easilly modulates, does so on the most powerful stopper. The weight explains why rear wheel skids are so easy, and geometry explains why front wheel skids are bad news - especially on motorbikes.
Typically with suspension, motorbikesput 90% of braking through the front - hense big twindisck 4 piston calipers on big rotors - but even superbikes have crappy little small rotored single or dual piston brakes. Even ahts enough to lock up a rear wheel easilly, and also why the rear brake on a motorbike is foot operated - as a hand is much more sensitive to modualtion, and hense on a motorbike the left hand lever is the clutch, and the right the front brake.
