...just curious, do cycles run RH shift/LH brake over there?
Up to about 1975, all motorcycles had the gearchange on the right. This was partly because of the way bikes evolved, with a seperate gearbox, & originally a hand change on the right of the tank, with a simple linkage to the end cover of the gearbox. The left hand side of course had the primary (chain) drive on it, so it would be more difficult to fit the gearchange that side. When Velocette introduced positive stop foot change in the 1920s, they naturally carried on with the shift on the right side. Even Harleys fitted right foot changes to their Sportsters until the mid-70s (to fit in with the "sporting" image). On the other hand, it could be argued that it makes more sense, as humans & most animals find it easier to co-ordinate limbs on opposite sides of the body, so if the clutch is on the left handlebar, it makes sense to shift with the right foot.
An added complication on Nortons, AJS/Matchless, Royal Enfield, Vincents, Velocettes etc (but not Triumph/BSA), is that the change pattern is reversed, i.e. you move the lever down to change up. Sounds daft, but there is a logic here. Most UK circuits are mainly right hand bends, because we tend to race clockwise, so if you are in a bend, you may want to change up on the apex, when laid over, but you won't tend to want to change down in a corner, so down for up makes sense, you don't want your foot caught under the lever when cranked over.
All this changed due to the US insisting that all bikes should have the shift on the left, for no good reason that I could ever fathom, & being the largest market at the time, everyone had to conform (Indians had the throttle on the left handlebar, & the left foot "suicide" clutch, but then , they were always different). All my bikes have the change on the right, because they all predate 1975. The last production bikes to have the change on the right were the 1980-81 Laverdas.
Only REAL motorcycles have the change on the right!
