Perfect Speed of Gear Shifting
1 - 20 of 25 Posts
You mean what RPM/MPH? That all depends on what you're doing. If you're commuting, you want to shift as low as possible for MPGs. If you're racing, you want to shift as high as possible for max power.
How fast do you shift? As fast as possible. Time between gears = loss of efficiency/mpg/speed.

At what MPH/Kmph.. what is MPG?

Shift RPM
From what knowledge I've gained from this forum, it appears that 5-7K RPMs represents the most efficient range for transmitting power and accelerating. As such, shifting in this band is preferable -- the upper part of the band or beyond when max acceleration is desired, and the lower part or even down to 4500 RPMs when in a gentle commuting mode.
I have read that shifting at too low of an RPM, say below 4000 RPMs is not desired, as the engine is likely to lug along, which is not good for the engine bearings.
My first day out with my bike, I was lugging a lot, shifting at 2500-3000 RPMS to get used to the manual transmission. In hindsight, boy was that engine lugging back then!

When you feel the bike stutter like its having an epileptic fit its probably time to bang up a gear.
When it's not going any faster its time to bang it down a cog.
problem with the cbr its got a narrow band between 8500 and 10,000, outside of that it moves slower than Australia Post.

My suggestion is to not over think it. Shift anywhere you want between idle and red line.
Where I shift depends on my mood and if Im in a hurry or not.
I agree with the rest, generally shift early for better mpg, shift late for more fun.
I don't think about gas. I get 75ltr every month from my bank. but Rs. 74/ ltr. in India. Mango men can't afford it(added unnecessary extra line).
I just shift up when it feels right, rarely wring it out beyond 9k tho.
The bigger question is when to shift down, especially if hard on the brakes into a corner. Even with ABS I've had it step out from a compression lock-up quite a few times, so I'm pretty conscious to lean on the front brake, use the rear to balance the bike only and shift down late.
I remember reading about blipping the throttle on downshifts and while I can heel'n'toe pretty well in a car, I don't get how that works on a bike when you have to squeeze a lever and twist your wrist with the same hand. Any advice?

Check out this threat.....there may be more

I highly suggest perfecting this technique. It will solve the problems you seem to have for downshifting.

I barely use the 6th, most of the time i reach 100kmph with 5th and suddenly there were too many vehicles blocking my way..
We don't have highway in my city... Can I just sell that 6th?

What sort of revs people sit on for normal riding about?
