Downshifting to go faster... The power a combustion engine produces tails off sharply as the revs go down (this is unlike an electric motor, which can produce a lot of power even when it's going slowly). It depends on the bike, but peak power might be at 6k or 9k or even 11k revs. If you're only doing say 3k and you want to accelerate, then the best thing is to shift down while you open the throttle a snadge, so the motor's now at say 4k, and you're still doing the same speed. Now, when you open the throttle up, there a load more power on tap. As for how to go slower, the basic rule is use the brakes. That's what they're for. This is how I'd approach an ideal junction: 1) clutch in, release the throttle and engage the brakes (that all basically one action); 2) as I slow down approaching the junction, I gradually go down the gears. keeping the clutch in all the time If I'm planning to stop at the junction 3) just before stopping, I engage first gear; the clutch is still in. Now I'm all set up to start off again in 1st whenever I want. If I wanted to ride on through the junction (e.g. I'm turning left at a give way) 3) I engage the gear I'm planning to pull of in (normally 2nd, but it might be 3rd at a large roundabout) before reaching the junction 4) if the road is still clear, then I release the brakes, and more or less at the same time gently release the clutch to the bite point, adding a little throttle. The idea is to get the bike moving forward again powered by the motor; I don't want to coast round the junction without any power, as the bike won't be stable, but I don't want to open the throttle up and accelerate away like Rossi. 5) By the time I'm half way round the corner, I've gently let the clutch out and fully in gear Dunno if this help. Probably it just makes it seem a lot more complicated than it really is
