if i wanna get a bit of a rush by accelerating quick (its just a gs125 but seems fast for me, at the moment) i take it up to 8k revs every gear (red line is 10k)

Because i never touch red line does that mean the engine will be fine? or should i lower it ?

You can take it to the redline if you want.

It will be fine, several occasions spent minutes at a time bounceing off the redline on the cg, proveded you keep the oil changes up 4stroke 125s gnerally with take allot of stick as them being thrashed daily is not optional its a requirement...
if you wan't to accelerate faster learn to change gears without the clutch...

what does it feel like going that quick? the most ive done is 70 on a steep down hill with the wind behind me..and that seemed VERY fast for me....

I feel like at that speed i have little/no control other than slowing down..

200mph (or near as damn it) is very, very quick and can only be done in the safety of a closed runway

consider, from a standing start to the chequer boards takes about 30 seconds and is a mile and a half - you can't even see the end of the course from the start it's so far away

I can't really tell you what it feels like as I cannot see very much or hear very much, it's surprisingly quiet in the bubble, head down looking at the rev counter relying on peripheral vision to make sure that you are still in the centre of the lane, adjusting for cross winds, watching for the timing boards etc.

when you shut off, sit up and squeeze the brakes and peel off into the return track you cannot see the timing boards you have just passed - this takes about 10 seconds before you run out of braking area, less at Elvington

it seems to take forever to get back to the timing boards

do not ever believe anyone who tells you that they have done this on the roads or that it is easy - even some of the turbos were only just making it and none of the Nitrous boys went faster than me

I got the 195.whatever only once and this was a run where every gear change was timed to perfection, my body position was perfect and every little appendage was well tucked in

oh yeah, all the while this is going on your rear wheel is spinning in a slow burnout too - my rev counter/speedo calculated speed should have been 207mph - so I was getting between 10-15mph of constant wheelspin

Kickstart has described the state of the BigCC bike rear tyre, obviously this is accentuated by the long swingarm but you have to imagine that the force of the air is like pushing against a wall, the tyre is bound to spin

mine looks like I have been doing slow burnouts all day


it's a rush for sure


totally different to roundy roundy track days (which I have also done lots of) but definitely something everybody should experience once in their life

riding a big bike flat out that is, not necessarily 200mph Wink

one of the guys videod a 170mph run (he was sitting up to accomodate the camera)

I'll see if I can find the link

If I'm out for a blast and there's a straight clear bit of road ahead. I always ride to the redline. In the first two gears I can feel the front wheel getting very light. But it never comes off the ground. Should I be able to get a wheelie on a 400 just off the throttle?

Also, does anyone find it completely different driving a car and revving it up to the redline? Doesn't sound or feel healthy in whatever cars I've tried it in. My mate is too scared to take his car past the 5krpm in his car when the redline is 7krpm. I'm assuming it's fine for cars to do this without breaking something?

I've, accidently, changed gear without the clutch, won't this be bad for the bike?

ProXimaCore - my mate has a Subaru Imprezza STi which he redlines at every oppurtunity!

It's fine to change up a gear without the clutch. But I woudn't advise changing down without the clutch. You should also use the clutch for changes between 1 and 2. If you are going to change up without the clutch then generally you have to be revving really high then let go of the throttle for a moment while you do the change then re-apply throttle.

clutch ?


never use it for upshifts on the track, it loses speed and overheats the clutch

often use it for gentle shortshifts on the road but not for spirited riding

modern transmissions don't need it



also, quite often bounce my car off the limiter - but is a 2.0 Turbo Diesel Embarassed

I normally change up at 12,000 on my RS. Upshifts without a clutch is ok, I can do downshifts without the clutch but try not to do it to often.

Same with a car, the redline is to be aimed for. The limiter is what you want to avoid. Very Happy

borrowed a SV650 when the bandit was in for a service...soon found the limiter on it, most depressing...

The CB box was very very clunky when I got it but after a week or so of doing clutchless changes in and amongst its loosened up....doing them on a bandit/old gixxer engine does the box no end of good, makes it really smooth

Very Happy

The escort rarely gets redlined. Well it does in first, but nothing else - Being an escort it goes to sleep just before 5k so theres no point.
