Hi. as treatened in the other thread im going to start a thread about the major problems with big inline 4's and how you overcame them etc, and any advice you can give me.

Basically my main concern is shutting the throttle off mid corner because i feel im going into the corner abit hot. Surely this is akin to smacking on the back brake. Any tips on how to overcome the slamming off the throttle reflex (ive just kinda grown it sadly). I understand its bad, but any tips on how to unlearn the reflex would be cool.

Also... i keep hitting the rev limiter in first, any tips on avoiding it (besides change up earlier). Its just it goes through first so fast now.

Oh and lastly, power wheelies. I assumed it was pretty much nail it in first and towards the end of the rev range it would come up. But oh no. Rev limiter time with hout but a slappy front to show for it.

Any tips would be well appreciated.

With the wheelies, shut the throttle off so the front dives and then open again and the front should then come up. You want to do this at about ~8,000rpm where the power starts so it has the revs up to the redline.

Not really got anything to suggest for the corning, with the rev limiter in first there isn't much to say other than change gear or accelerate less, has the bike been down geared?

Isn't having to shut off the throttle mid corner a result of going into the corner too quickly in too high a gear? I may not know a lot about riding really, but I vaguely remember overcooking corners and ending up having to change down midway through them and drag the rear brake.

Oh well, just a suggestion anyway. Seeing as it's officially almost Saturday, I finally get to go home and ride my bike again! Very Happy

This might sound pedantic (its not meant to) but why not slow down a little and build up your speed as you get used to the bike. You've only had it, what, a week? It'll take time to get to know how much grip you've got (which will also depend on road surface and weather, obviously). I'm no biking genius and I still haven't fully got to grips with my own bike yet (lots more milage this year should see to that though! Wink ) but surely going in slower and pinning it on the exit is way better than over cooking it before you make the apex. Penny Coin Penny Coin

Also probably because your not used to it. I got past that quite quickly by recognising what the exhaust note is like just in the middle of the power as I'm hard on the throttle. Haven't hit the limiter since.
Otherwise... Change up earlier you numpty! (Sorry, couldn't resist!) Wink

For first gear red-line; just get used to the engine note and remember to think Smile.

For power wheelies; I don't know how great that model CBR will be for them with standard gearing. But about mid revs or a bit higher, throttle off then snapped on again. Once you get used to the bike you can probably bring the revs down.
Clutch is definitely the reccomended method however Thumbs Up.

There are worse things than you can do compared to closing the throttle. However it's definitely not a reflex you want if you throw highsides into the equation.
Best thing is to accurately guage the corner Smile. After that, leaning more usually does the trick in most situations.
If you've got enough grip to mess up the weighting on your tyres, you've probably got enough to lean more Smile.

The way I'd do it would be to completely rebuild my cornering technique from scratch.

Get all your braking done before you actually turn in to the corner, so you're down to a manageable speed, then get the throttle cracked open slightly ("maintenance throttle") so the bike is driving round rather than coasting.

This should eliminate the need to shut the throttle when you're mid-corner - which can unsettle the bike by loading the front wheel as you decelerate.

Once you see the corner opening up and the vanishing point is recognisably moving away, you can get upright again and open the throttle more as you do so.



Okay, so you'll probably ride through a lot of corners and think "I could have gone a bit faster" - I know I do - but I reckon that:

a) that gives you a bit of a margin for safety on the road, and

b) it's part of the learning process - you'll get better with experience.

some good advise already posted, just remember:

brake before the bend
select the right gear before turning
slow in=fast out
look at the exit/where you want to go (if you get fixated on a hole in a hedge you will be in it-trust me!)
It's better to go round a bend to slowly and think, 'crikey I could do that 20mph faster' than go too fast and crash

Take it easy until you are used to the bike.

As people are going on about safety... I would definitely reccomend having a look at the Police Bike riders manual (forget the exact name right now Smile ). Loads of good stuff about how to read the road and predict what's going to be coming up.

Also definitey get all your braking done in a straight line if possible on the road.
Riding on the track has shown me that you can get a suprising amount of braking force while seriously leaned over, with the front brake. However track conditions are going to be much, much better and I'm riding a sorted track bike, sorted suspension and sticky, hot tyres.

I pretty much agree with whats been said allready, it is definitely a case of entering the corner at the right speed and in the right gear, riding through and opening up on the exit. G the book you mention is Roadcraft.

I find i trail the front pretty late into the corner, crank it over, feed on the power, and then sometimes if thats a bit hot rather then slightly close the throttle i do it a bit savagely. Kinda binary styley. Its weird because i have alot of throttle finesse on the way up, its just on the way down.

Im going to go and try that power wheely thing today, always annoyed me that wheelies are a great example of chaos theory. At 35mph at 7k revs and dropped nothing will happen. At 8k revs the front will happily rise a bit, at 9k it will flip. Small changes make big fuck off differences. I was originally under the impression the bike did all the work in power wheelies... but it seems not. As i may have said, when i got over enthusiastic with a pillion on the back it was beautiful. Cruised up and then i back off and it cruised back down. But usually when i nail it it just slaps the rev limiter within seconds.

Other point about 600's (could be just my rwu forks coupled with no damper) but when i try and power wheely and it dont come up, it gets very light and dear god does it have abit of a hizzy fit at the bars. And yet i can clutch it up merrily and rag off and it never complains. Odd

Too many cylinders, too much to go wrong. Common as muck, everyone has them. Expensive to service (16 valves = 16 shims!), expensive to insure, expensive to crash. A liability on crap road surfaces. Generally just don't like them.

I overcame these problems by going out and not buying one, choosing a big single instead Wink Laughing

Looking at cornering more objectively for a second - you need to play to your strengths. It's what all the greats in any motorsport discipline do. From your familiarity with your limiter it would seem that you have discovered the strength of 4 cyl 600s i.e. rocketship acceleration. Therefore, play to your strength - there is no point in going in hot, changing down, unsettling the bike, braking or any of that - jeez it hurts my head just thinking about it. Get it all set up nice and early - brake in a straight line, and get any gear changes out of the way, think about your body positioning, look as deep through the corner as possible (all the time) and tip her in. If you are in the correct gear you should be able to hold a steady throttle through the corner before accelerating progressively harder as the corner opens up and the bike sits up moving through peak torque as the bike gets straight and charge for your redline.

You'll feel smoother and more in control - and even if you think you could have gone faster, i'll bet you were going faster than the too quick, shut off, panic, power on technique you are using. Other bikers will acknowledge your smooth technique, cars won't even see you for dust.

You can play with this the whole time. Every corner can be smoother than the one before - did I time my blips well? How smooth was the weight transfer? (both of these will help you immeasurably in the wet) Did anything happen that i didn't expect? What did I learn this time? Could I have achieved the same result but been more relaxed and smoother? etc etc

Power wheelies etc are fun for a while, but nothing beats the sensation of really, really hooking a string of corners together. It's what your bike was designed to do...

And read Roadcraft - as many have stated here: try following a Police rider through the twisties on his Pan European and it is a masterclass in SMOOTH riding - and boy are they travelling...
