Also try moving the handlebars either back or forward to suit your arm length sounds daft but it works also the levers - put them in a position that is comfortable
I have absolutely no idea how 'rejection' works. Obviously the purchaser gets his money back, but who takes the 'hit'? Is it the dealer? Don't see why it should be, not his fault. Can he return the machine to Honda UK and get his money back?
Plainly the machine (even if fully repaired) can never again be 'new' and can only be sold on as 'used'. Anyone actually 'know' rather than guess?
