After playing with my VFR400 the other day at higher revs through corners, I was noticing my rear has more grip under acceleration than I thought which made me wonder...

Exactly how much power do all you other guys put down after you've started to drive out the corner? and at what angles do you start really putting the power on?

I've no plans to push rear grip limit on the road but I am curious to know what bikes people push to what limits, just for curiosity. Out right power doesnt interest me in a straight line anymore, neither does top speed, but right now I'm trying to nail getting on the power out of corners.

[I know this is really hard to answer specifically cause of what tyre you have on what bike, and what power the bike has etc etc, but I'm interested none the less]

Not enough most of the time.

I am often exiting a corner thinking "Well that was shite...more power Igor!"

Practice makes perfect I guess. Thumbs Up

I would say that depends on how powerful/quick the bike is and your mentality of what road riding is all about.
Me personally,i dont need to lay down loads of power coming out of a corner coz my bike goes plenty fast enough at cruising speeds anyway and i don`t treat the roads like racetracks (well actually i do "sometimes" but only when i get giddy Laughing ).
On the rare occasions that i test the limits of the rsvr i only use its power when its fully upright.It`d be dumb to try it any other time....especially in the corners at extreme lean angles.

It was a different story on my old 6rr and rs125 though coz they didn`t have as much instant power low down in the rev range.... i had a lot more fun on those bikes than i do on the 1000.
i`ve never had a 400 but i think it`s safe to say you could really give it some in the bends and not have to worry "TOO" much about losing traction.(with good rubber fitted).

HTH

Enough throttle to get me round the corner as quickly and safely as the road conditions allow Cool

According to Keith Code and the California superbike school you should add throttle as soon as you have leant the bike and as you go through the corner. Obviously you don't put too much throttle on immediately but you add the tiniest amout of throttle at first, and then progressively roll on. It makes a heck of a difference.

It's difficult to say without on board or telemetry or without constantly riding on a dyno.

Remember, that just because there's say, 10,000 rpm showing on your VFR's tacho at a corner's apex, doesn't mean that you're applying the power you see at 10,000rpm on a VFR's dyno readout - as I doubt you're at full throttle at that point.

When apexing a corner, I'd have the bike accelerating just enough to get the bike stable in the corner, before winding on the power once the corner's open. Doesn't necessarily mean I'll end up winding it on to the throttle stop, as it depends on the road I'm riding, conditions, what the road does next, what's ahead of me, etc.

Too many variables.

On modern bikes you want to be gently accelerating through a corner to keep maximum grip as Marjay suggests - this is because you want to 'weight' the wider rear tyre which has more grip in total.

As far as getting on the power hard, it depends on the situation. Slicks on a downgeared R6 in second gear I've been able to go straight to wide-open-throttle from knee down at an apex.
On a road with an icy sheen with a cold ten year old tyre on the zx9, a very gentle application has seen it spin up.

The main thing is to only get a little bit faster every time, that way nothing too bad will happen when you lose grip, as you'll only /just/ do it.
Of course, the track tends to be the safest place to do this as you can do the same corner over a hundred times in a day; so you can concentrate on you and the bike, not where the roads going.
