Hey guys, just a quick question, i failed my CBT recently due to what's mentioned in the title. Even though i asked my instructor, he wasn't clear on how to use the clutch properly or how to go round a corner in what gear or anything like that. I'm wondering if any of you guys can give me a basic 101 on all that before i go back this weekend? Any help on this would be so helpful, not passing was the worst feeling and i'm very eager to pass this time round,

Cheers,

Bit of a varied question here but okay, i'll bite Laughing

Sorry to hear that you didn't pass, but did your instructor tell you that you "didn't pass" or did he say that "you're going to have to come back for more training?" because its not a test, therefore you can't actually fail Smile

What gear - So you've accelerated up to say, 30mph, which is the normal speed limit in residential areas and you come to a junction where you would like to turn left. If you feel like you're going too fast for the corner, then release the throttle, apply the front brake (or the back, whatever), and just click down a couple of gears when the revs drop (I usually start to change down at about 3500 - 4000 on my 125). Just change down to whatever gear feels a nice speed to get around the corner... maybe 2nd?

Clutch control - Are we talking about using the clutch to change gear, or pull away, or manouver at a slow 'walking pace'?

Probably not a brilliant explanantion of gear changes etc, but it really is something that you pick up yourself on a bike. You'll be able to feel when the bike is in the wrong gear (either the bike's revs are too high, and the engine pitch is too high, or too low, when the engine pitch is very low and its not giving you enough 'energy' to pull). Even if you do hit a corner a little too fast, 9 times out of 10 you'll be able to lean the bike around the corner and get away with it... but for the love of god, don't touch the front brake whilst in the corner (I made that mistake) Laughing

Hope it helps. Smile Good luck next time.

Thanks for that, and he didn't really say anything, there was not a lot of input from the instructor(s) at all,

And yeah lol i should've been a bit more precise in my question, right so say i'm coming up to a corner in 2nd-3rd, before i reach the corner i brake, do i then need to switch down a gear and do i need to apply the clutch through the corner or just let go of the accelerator?

And yeah it's next Saturday so fingers crossed i won't muck up this time Thumbs Up

I suggest asking him/her to explain things properly. You're paying for it.
If he's a gibbering goon or a mr angry type then ask for a different instructor.

If you're the meek type then time to man-up abit and don't be afraid to ask them to repeat instructions.

Coming to a corner in 3rd (at 30) >> Position yourself on the road >> Release the throttle >> Pull in clutch >> Flick down to 2nd >> Release clutch and add a LITTLE power (just to make sure you'll get around the corner without stopping Laughing) >> Lean it around the corner >> Accelerate away, flicking back up into 3rd if needed. Smile

So you made it to the on-road part of the CBT? Well thats a good sign.


By corner, Im gonna assume you mean a junction, like a T Junction.

When coming up to a junction, Slow down in advance (The instructor wants you to do this) by breaking lightly, Change down gear from 3rd to second, using the clutch, then second to first when you've stopped, again using the clutch, that is assuming you need to stop for that junction, for poor visibility or a solid white line.

if you mean an actual corner... well you should have an appropriate speed for the corner, not having to lean right over to get the bike around, stay in gear, dont hold the clutch in, Keep on the throttle, but don't rev it hard or you could loose traction (more a case for bigger bikes, ive never had that problem on my 125)

Depends what you mean by "corner".

You should very rarely have to use the brakes on a bike - essentially they're necessary when coming to a stop, or in an emergency, or when you're larking around and caning it from one bend to the next.

Anticipate the corner, come off the accelerator and the bike will lose speed quite quickly by itself just through engine braking. Change down when the speed of the bike dictates it, that's only going to come with practice, you will nob up plenty of gear changes at first. If you're going to change down, then do it before the corner, not in it.

Use the clutch very briefly when changing gear, or when coming to a complete stop, moving off (get off it fast though), or when moving very slowly (through traffic or in the daft manoeuvres in the module 1 test) - don't hold it in while you're travelling at any sort of speed.

And your trainer should cover this. If he thinks it's beneath him to answer then he's not a fit person to be doing basic training, and the DSA would like to hear about it.

Did you make it to the on-the-road bit?

you should have already been quite comfortable with turning after spending half a day riding in circles and figure of eights?

Sounds to me like your instructor isn't particularly instructatory. You should be able to get feedback about where you're going wrong if you're not 'up to scratch' with riding a geared bike. And what you've mentioned in your posts pretty much covers it all.

Clutch control; when you're moving off you find the 'biting point' (when the bike starts to pull forward) slowly releasing the clutch. When you have this point, give a few revs and feed the clutch out slowly to accelerate to a steady pace, then throttle control takes over for acceleration.

Clutch control for gear changes; when you want to change up gently push the shift lever up (this is pre-loading.) Simultaneously squeeze the clutch lever about 1/3 to 1/2 in while releasing the throttle. The shift lever should click up to put you in the next gear, but it might help to push it up a little harder to make sure. Now feed the clutch out while increasing the throttle.

Changing down; if you're slowing for a corner while in 3rd, slowly release the throttle to bring your speed down. Use some brakes if you need to slow down faster. When your revs drop to around 2k (best not to look at the rev counter, you'll learn to judge it by the tone of the engine) squeeze the clutch in, again about 1/3 - 1/2, and at the same time click the shift lever down. Feed the clutch out.

With a junction where you might or will have to stop, simply click down a second time with the clutch squeezed, use your brakes more to slow you and 'feather' the clutch to crawl forward.

As for cornering itself, the most important thing I could tell you is LOOK where you want to go. The bike will follow. Take it easy around corners at first, until you get used to judging the speed and angle etc. It becomes second nature.

If you're anywhere near me we could meet up for some practical pointers, as it's much easier to show someone than tell someone how it all works. Although it's not too hard to put into practice and you should get it without too much trouble. Hope that helps.

Thanks everyone for your replies so far, i have a much better understanding now of what to do when cornering etc,

Basically what happened on my CBT is the guy just gave me a bike held together in places with duct tape on the dials and other places, and told me about the biting point...that was it,

I asked a few times what to do but it was made no clearer so for the first part of the CBT i was very much guessing what to do, which obviously resulted in some unpleasant experiences and when it came to the road riding obviously i was not allowed out on the road, (i agreed with this as it wouldn't have been safe obviously, but it wasn't like i hadn't tried to actually even find out what to do and how).

All in all i felt cheated out of my money at the end of the day, but i've got it rebooked for half price this Saturday so i'm hoping it all goes well, just one quick question here, assuming the speed is reasonable for the corner, would it be okay to go around in say 3rd gear, or is it always the best idea to go down to 2nd or 3rd?

You can go around the corner in any gear, 3rd, 4th and 5th (6th if your bike has 6 gears)

It all depends on your speed, the corner its self, and the engines revs

You really should discuss your experience with the DSA - you should not have left not knowing how to use the controls correctly.

Also, at what time were you 'sent home' - CBT is supposed to be a full day's training and so if you were sent home early - you are still 'owed' the time.

For future reference - we accept that all of our clients learn at a different pace - if somebody needs to return for further training (it is not a pass / fail), we do not charge - however long it may take Smile

Well we all started at around 8AM and i left at 1ish, that's when the lucky few went out on the road,

And although it was a pretty awful day, i gotta say, riding a motorbike has gotta be one of the best feelings, damn can't wait to get back out there Very Happy

Damn right it is. You have your own freedom, and freedom is brilliant. Smile just wait until you have you own bike parked in the garage that you can ride whenever / where-ever you like, its a good feeling. Smile

Firstly, either the school or the instructor you were with is crap. Talk to DSA about it, I'd even try to get a refund especially as you got half of what you paid for. Go somewhere else, even if it's a bit further away/harder to get to. The CBT is a days training as people have said, and you pay for it. One guy who did his CBT at the same time as me stayed on the pad when the rest of us went out. He didn't get sent home, he carried on with the off road practice.

Secondly, contact these people and ask them where we should send the bill for the training we've given you. We are doing their job after all; they should be doing everything short of riding the bike for you to teach you how to ride safely on the road. That's what you've paid for. CBT isn't a pass or fail test, it's Compulsory Basic TRAINING. They're supposed to train you.

I'm rather annoyed about this on your behalf Rolling Eyes don't let them dick you around and take your money.
