MC28SE Gearing when de-restricted

Sun May 25, 2008 7:28 pm » Post: #1 » Download Post

Reading through this website I have found some references to the MC28SE having it’s gearing set by Honda to keep the bike at its 112MPH Speed limit.

Is there any truth in this, if so, does anyone know what I should change it too?

Are there any benefits to changing it or leaving it as it is?.

Cheers Rob

The gearing makes use of the available power, but to be honest the NSR (or any road-going 250) isn't about going fast in a straight line! Even de-restricted I bet you won't want to re-gear it too far. Remember, get caught at anything over a ton and you're likely to lose your license! Better in my opinion to keep it on the twisty B-roads at 80mph or so. Low gearing has a tendency to keep you off the main dual carriageways and motorways too... environments the NSR was never designed for!

My MC21 is geared at the moment for about 135mph @ 12,000rpm (15/40 with an F3 box on M6/C6 top gear) but only because I was short of a good 14T front sprocket and Steve and I used to chuckle at the TT-style take-offs with the 60+mph 1st gears! I'll be swapping that soon and dropping the top speed back down to 125.3 @ 12,000rpm, and then maybe even going back up to a 42T rear now that I don't blast down the A30 to his place any more.

14/42 will give me a top speed of 118.5mph, but it won't half be fun getting there. There won't be a lot that will stay with it then, as it already out-drags Steve's F3 in 1st~4th on the current gearing! Very Happy
