This is purely a thread just for the poll as I want to see the techniques used coming up to a corner. Not a traffic light or a junction where you are stopping but where you have to brake and go down at least a gear.

Thanks! Thumbs Up

EDIT: Thought I put in an option for other but clearly I didn't fill it out properly. If you do none of the above please post a comment below and don't tick any of the boxes.

Depends entirely on the corner and speed if I am honest... Not a very good poll answer Sad

I said option 2. Option 1 is fine generally but a throttle blip is obvously better for your transmission, reduces the weight shift and chance of locking the back wheel and of course, most importantly, sounds cool Cool

Option 3...do you mean you're only reengaging the clutch as you start to apply a little throttle through the corner, i.e. once you're off the brakes and already starting to lean as that sounds like you're going to unbalance the bike pretty badly and give yourself a lot to think about in a short space of time.

The only time I use the clutch is when I pull away, or stop.

Hmm, sort of. i have a mate who does it and hear people doing it all of the time.

Basically coming up to the corner and grab the clutch sort you gears out. So maybe down two and then lean in. Just as you start leaning back up straight, let the clutch out with the throttle. Much the same as a lot of folk do in cars.

And binge, always wondered that. If people on the road with crossers/enduros used the clutch or not...

Gonna make a thread tomorrow about car downshifting, where should I put it?

He who doth downshift without blipping ye olde throttle, shall face being hanged in front of the villagers!

In my eyes, downshifting without an appropriately measured out blip (depending on rate of deceleration) is just as bad as upshifting without letting off the throttle. 'tis the same principle; rev matching, clutch forgiving, smoothening out, better control.

Free wheeling round corners is idiotic. You should brake as you approach the corner an select the right gear and line and then give slight acceleration as you take the corner to settle the bike. As you pass the apex you can then get on the gas as you straighten up.

You saying that reminds me of when my bike bogs down, I keep it pinned but grab the clutch and go down a gear at the same time. Sounds lush but only done it a couple of times as I fear for my little engine Laughing

free wheeling round corners means you have no engine braking to slow you down if you go in to hot, and you tend to speed up when you free wheel round corners.

You should have a neutral throttle mid corner, not accelerating but throttle should not be closed. This avoids the jerk when you want to get on the gas coming out of a corner whilst still lent over.

I blip but thats because i spend 90% of my biking life on a race track where it is needed, and thus becomes habit. However if your bike has a slipper clutch or quick shifter then you dont really need to blip.

Blipping helps avoid rear wheel lock up. On a track when the rear wheel is only skipping along the floor under heavy braking it is easy for it to lock up, also you are very high in the rev range. On the road you rarely brake that hard and are rarely that high in the rev range. It still helps but its not as vital on the road.

Dunno. Don't so much blip the throttle as slowly increase it as the clutch is let out. If I lose a few MPH in the process I'm not going to commit seppuku over it.

I voted 2, then I re-read it, and realised, that's not what I do. Mine is similar to Hmmmnz. The motion is pretty fluid and is done in a matter of split seconds that it now blurs and has become subconscious.

I make sure that I release the clutch after every blip so that I know what the engine and back end are doing in terms of drivability through and out of the corner... such that I'll be at about 5-7k where the bike is stable in its powerband on a smooth constant throttle. Also more importantly keeps the bike stable going into braking since the back wheel is less inclined to hop.

Going in too high a gear will make you run wide of have to push it at a much tighter lean angle. Too low, you risk unsettling the bike and chopping throttle mid corner. It's the only way for me to tell which gear to go in when going on a spirited ride on unfamiliar road. Then once that's all sorted, it's body and bike positioning BEFORE i go into a corner.

Not meaning to slag the power rangers (because I am indeed one)... a lot of things I saw on the road in the corners was a combination of the above paragraph which made for some very hairy moments - brake lights going on mid corner... running wide etc, but that's another subject entirely.

So blip as you shift is for me... unless you have a slipper clutch and quickshifter!

Close throttle then open throttle for most corners. Usually sorted out which gear I want a fair bit before.

2 Smoke
If I’m out on the 250 NSR, I’ll be on the brakes a lot.
Approaching a good bend, I’ll be hard on the brakes, and down shifting to keep the motor spinning.
Once into the corner, I’ll be slipping the clutch, a lot, and keeping the revs up,
Once I’ve hit the apex it’ll be full throttle, if I’ve dropped out of the powerband there will have to be more clutch slip until I hit it, then its clutch out and away we go.

IL4
Got to say if I’m out on the CBR6, unless I’m in hooligan mode, I very rarely use the brakes with any great force.
If it’s a road I know, I will be matching revs and using engine braking to slow down.
I will be using the clutch and throttle blipping to match the revs before I tip it into the corner. Once into the bend I’ll be feathering the throttle up to the apex, once I’ve hit the apex I’ll get, smoothly, on the power to exit the corner.

Big Single
Leave it in fourth! Laughing

Shocked . Nasty idea in a car, let alone a bike.

wtf??

that sounds like a very bad idea.

id love to see someone do that round a long sweeping bend, the crash would be funny. would look like the riders just fallen asleep on the bike Very Happy

Hmmmmmmmnz, TOT and supZ, that is what I meant by the second option.

Keith, I know. I don't do it Laughing just saying people do.

And supZ, I generally mean junction where you just brake and go, not stop if you get me. Hard to explain...

Blip the throttle on down changes if im caning it or racing friends, if im just cruising i change down one at a time. So usually its blipping.

It depends how fast you're going into the corner, the only reason you blip is to bring the engine speed upto the speed of the rear wheel to prevent it locking up. As when you shift down, you obviously need higher rpm's to get the equivolent road speed.

If you're riding smoothly, using proper clutch control you shouldn't need to blip.

I would say that using properly throttle control and blipping the throttle to match engine speeds there is no need to abuse the clutch by slipping it for a slow but smooth engagement.

All the best

As someone said above (can't remember who or be assed to look up Laughing) it sounds good Very Happy I think it sounds awful when someone doesn't!

I sometimes do clutchless downshifts, but usually I blip the throttle just before releasing the clutch. I change down one gear at a time.
