ok i have been riding my nsr for about 1 week now and i hardly stall at all now, the problem is when i used to have my moped i could happily filter to the front of a queue and know that as it wasnt geared i could just twist, and go Laughing
but now with gears i dont want to filter to the front of the queue as i am scared in a rush to accelerate fast i will stall it, so please any tips on how to acelerate fast are really appreciated Sad
if i realease the clutch then apply more throttle it doesnt work, its just stalls Brick Wall

The trick with 125's is to keep the rev's high even with the clutch in. Then when the light's turns green, nail it!

Just find somewhere quiet and keep trying to bolt from a standing start. I spent an evening playing around when i got my 1st 125, and it helped one hell of a lot.

Go and find a car park and practice slow speed riding, you can always keep the revs up, slip the clutch and use the back brake to balance the bike. You just need to be smoth with the clutch and keep the revs up as you accelerate away from the front of the traffic. Practice does make perfect, if you don't feel comfortable then stay safe instead and hang back.

Use your back brake and clutch to control the speed. Just the same as when you were doing your U turn on the CBT. 125's are fairly gutless so you can have it reving quite high and still control speed with rear brake. Once you mind switches and gets used to using your right foot at slow speeds to control speed instead of your right hand you'll be in complete control

Practising hill starts in heavy traffic (ie stopping every 20 yards) is a good way to get used to using decently high throttle and slipping the clutch, along with using the back brake to hold you.

Basically, it's all about plenty of revs and letting the clutch out gently. Or at least that's the way I do it.

Just rev it really high, and slip the clutch slowly at first.

You'll soon learn how fast you can slip the clutch, whilst keeping the revs up and getting decent acceleration.

Never done a U turn on your CBT then huh? You do it againt the rear bake the whole time your on the throttle. Gives more control. This is pretty standard stuff and one of the first things they teach you.

siting at the light

when i started this was my method

Arrow Wait till i rekoned it would be amber/green soon

Arrow Have foot on rear break

Arrow stick revs between 3k - 7k (proably 5ish)

Arrow let a bit of pressure off the back break

Arrow feed the clutch thru until the bike tried to move

Arrow back off the clutch

Arrow let the back break go / let the clutch go further than the point id jus pulled it back from


soooooo hard to a) remember how id it b) explain summin u dont think about ne more

Must admit I'm crap at accelerating fast on the CB500, mainly because I never really try. I am always faster than the cars so that suits me.

However, last year even Cliff on his wee 100cc thingy was faster from standing than me. Laughing

Must work on that!

I didn't do the CBT, they didn't have that 29 years ago when I got my bike licence.... it was "ride around the block at 30mph & then do an emergency stop when I step off the pavement in front of you"
Which was changed to "do an emergency stop when I throw my newspaper into the road" after the tester was run over by a guy on an identical bike to the one my brother was riding during his test..
And no, I have no need to use the rear brake during a u turn, why would I? I know which way the throttle works therefore I have been able to do u turns without nailing the throttle WFO for the past 29 years....

Its just a matter of getting the revs up and not 'dropping' the clutch, if you do this expect to flip it! As allready said, it is clutch control, wouldn't try it in traffic till you are confident.

Nahh, just make sure you've got as much weight as you can muster over the front end and drop that clutch like a bitch that doesn't want you to have a bike. Wink

Yea, is possible, but a lot more likely it'd just stall.

To get a really fast start you need to be revving the bike to about the redline.
Then feather the clutch so that it's not all the way out, let the clutch out slowly so that the revs stay the same as your speed increased.

You actually want the revs to be about 1k before the red line on the NSR I reckon. Obviously the revs will drop a bit as you let the clutch out.

Start by practicing doing the same thing but at say 7k or 8k.
Try and keep the revs constant and slowly realease the clutch as you get faster and faster. You may need to turn the throttle a bit to keep the revs constant.

As has been said here already,learn how to slip the clutch the get used to using more and more revs until you've got fast getaways sussed. It's very easy to get overconfident,then when you want to do it,get it wrong.
I found this out about a week after i got my RD125LC,i tried to make a fast getaway in front of some mates,got it a tad wrong and the front went vertical scaring the life out of me Embarassed It did look quite good by all accounts but i was very lucky not to flip it and look very,very stupid.

Its not so bad on these Road 125s as they have very short 1st gears, the RS Aprilia will do only about 35mph in 1st. Just rev it to about 1000 under the redline. Try and hold it there rather than blipping the throttle to keep it there and then gradually use the clutch, don't just dump the cluthc and hope for the best. It won't flip an NSR or an RS coz they are so heavy and have no real power. I find myself using the clutch till about half a sec before shifting up into second. So on an RS Aprilia you would be holding the revs at about 10000 and try and keep it bang on there. If you go into the over rev by applying too much throttle it won't go anywhere and if you let it drop below 8-9000 it also won't be going anywhere that fast. Everytime I do a start on the Honda RS125 its like you don't know whats gonna happen lol, it weighs nothing (70kg semi dry) and has 45bhp and that 45bhp drops to 5bhp the moment it drops below 9000rpm. I almost looped it first time out just by letting the clutch out just that bit too much, got it on Video and it wasn't actually that bad lol. If you get a decent start the front wheel is just hovering above the ground most the way in 1st or just as you slip the clutch that last little bit and its a tall 1st gear too. Considering it does 60mph in 1st gear you don't seem to be slipping the clutch for all that long, in the pic below it just shows you what it does just under throttle in 1st gear, so long as its above 11000rpm, it only goes down when you shift into 2nd. With the Honda RS I rev it to about 11-12000rpm and try and keep it as near to that all the way until the clutch is fully out. The key is just keeping the revs consistent all the way, so from the moment you initially start to move off all the way till you have no more clutch to release. Practice makes perfect.

Its more of a hop than a wheelie lol, but its quite impressive when you think that its a 125 that goes 60mph in 1st gear and it does it unintentionally just under throttle however much you sit over the front with no clutch. Could you imagine an Aprilia RS125 wheelying under just opening the throttle in 3rd gear? lol

Yea just practise makes perfect. Way i did it was go to an industrial state, give it a fistful of throttle, and slip the clutch out gradually.
The more confident you get, the quicker you let out the clutch.

SOMEHOW i managed to power wheelie my NSR in 1st a week ago. Didnt mean to, just messing around with a mate, and in first from dead, the front came up to a very good height. Haven't emulated that yet Sad

They always say the NSRs are quite quick acceleration, they probably have very short fisrt few gears, whats the speedo showing when you redline it in 1st?? My Aprilia wouldn't do that in a million years lol, the fronts just glued to the floor. It'd wheelie if you tried, but anything will.
