Bad form to follow up my own posting, I know, but I have just come
across a programme on-line which is supposed to calculate this stuff.
According to this programme (which can be found at
http://pw1.netcom.com/~sgalaba/mph.htm#GearSpeed), we should be getting
55.97 mph at 3000 rpm in top (with 155/80R13 tyres). I don't believe
it!
Somebody, somewhere, must have the official Triumph figures, surely?
Please? Pretty please?
