I have a 2003 GSXR1000 track bike for having fun on track days here in the UK.
The bike came fitted with the Endurance rear and Medium front. These have felt fine to me but as they are needing to be changed I am wondering about getting Medium on the rear and Soft on the front. I'm no racer but I do ride in the fast group (for the UK guys I get round Oulton park in about 1:58 though I believe there is plenty of improvement to come).
Does anyone know how much extra grip I might get and how much quicker they would wear out?
Thanks

Great information Bullet and Steve.
I have just bought a GSXR1000 track bike in the UK and the tyres on it say NTEC Sportmax. This doesn't seem to fit with what has been said. There are no GP211 etc numbers.
Also they say made in France.
Any ideas please?

Now instead of hanging a full butt cheek off just move somewhere between one to three inches to the side when setting up for the corner... basically very little, see if this lets your outside knee (from the knee to halfway towards the groin) come in contact with the tank more as this is where you will be holding on best (the stronger Quad muscles). If all your contact is close to the groin (abductors) then you wont be able to maintain that pressure for long, best to use the quads which are far more powerful.
Picture that your outside knee can be rivetted into the tank...to get to that position most people need to move a little back in the seat, not so close to the tank, this is where it's important to refine this with a coach in person, as everyone is an individual ("no I'm not!"), now in that position further back from the tank, is it easier to get the upper body lower? can you easily get your knee way further out than before? Does this position give you more room for your arms and potentially for some... the beer gut? Do you feel more stable should you hit bumps? How about how much lighter you can relax on the bars? easier there? Can you last longer at trackdays doing this? with a more stable bike and less lean or more speed with your knee down earlier (big goal for some)? Most importantly or you, how is your footpeg weight? A bit better?
This sounds good but what is this guy doing?

Ok, I worded it very badly but I think what i'm getting at is this: Would anyone on here think about trying to go into the corners faster to improve lap times? Just seems to be the opposite of what we have read/been taught.
-
Hi Guys,
Mike3000 - What is he doing that is "exactly the opposite" of what we think?
He was making all his time on the entry to the corners. We focus on not charging the turns.

Come on you guys. Here is a guy visibly riding faster than the very best in the world and doing exactly the opposite of what we think is the best way to ride fast?

Hi all
At Valencia last week Jorge was clearly gaining on everyone else on the entry to the corners and not losing anything in the corner or on the way out.
Any ideas how he did that?

Hello AceBobby
I can't wait to hear your comments on Cascades. Lovely corner but I can't work out how the theory of Late quick turn (which I completely agree with and feel working) matches up with how fast riders go round there.
Have a look at a google image from above and then watch footage of the BSB boys.
Its the 1st left hander after the start finish straight.
Have just thought, maybe this should be a different thread?

Great videos Bullet, really useful to watch.
How different would your lines be on a 1000cc bike?
-
OK I think I am finally getting it. They're not really turning where I said, they are just moving the bike in a little and then making the actual turn later at about the white line....
The only trouble with that is it doesn't look like a very quick turn. I'm sure I'll work it out properly eventually.
Bullet, thanks for the advice. I'll carry on doing what feels right and not worry about it. I'll keep mulling it over though.
Anyway heres a clip below
Jaybird, this clip is obviously from the race but they were doing pretty much the same in qualifying and Biaggi definitely doesn't need to defend his position.
-
Cobie, unfortunately I didn't record it and I can't remember how early they got on the throttle. The MotoGP boys will be there soon so I'll watch more closely.
Bullet, I completely agree that you need to turn in later rather than early but the WSB boys were not turning late and thats why I'm confused. My turn in point is similar to yours and it feels like it works. I can't imagine starting the turn as early as they do.
I can't really understand how the tyres and bikes can make that much difference. This seems to mean that as I get quicker I will need to turn earlier. That can't be right, does anyone have any ideas?

OK I'll tell you what I saw. This was qualifying so it wasn't a defensive line.
They started the turn just over half way across the pit exit lane. In between the google earth writing and the white line.
Does that make sense to anyone? That looks way to early to me but obviously these guys know what they are doing but I am struggling to understand it.

Hi,
Yes that makes sense, but I'd still like to know where you would put the X to compare with what they were doing. Then I'd like to understand why?
Thanks

Hi all,
My question is about late turn in points. I tried this out after reading TOTW 1 and 2 and soon became a big fan. I did level 1 recently and this reinforced what felt naturally to be a good idea.
Have a look at this pic of a right hander though and tell me where the X would be drawn on a level 1 day. I can't make sense of where I saw the WSB boys turning.
UK readers will recognise the corner straight away.

No I don't stand up on the track. I stood up to exagerate the pressure on the peg. The bike does steer by putting pressure on the pegs.
This is bothering me because its a fundamental part of the CSS system that you can't turn a bike without counter steering. Well yesterday I did??? I believe I could do the same on the no BS bike. I do not believe that if the no BS bike rider stood on one peg only and leaned his body out that way that the bike would carry on in a straight line.
I'm questioning this because I want to understand the science of riding a motor bike.
-
So, I have read advice from racers telling people to pressure the right footpeg to start the bike turning right. I have though to myself that these guys don't know what they're talking about. They might bee fast but they don't know why they are fast. If they had read Keith's books like I have they would know that te only thing that steers the bike is counter steering.....
Anyway, today on the motorway I tried a little experiment. I stood up on the bike and lifted my left foot off the peg. Guess what happened, the bike started leaning and steering to the right. I must have countersteered without realising. I did it again making sure there was no pressure on the bars with the same result. I even tried it with a little countersteering to make the bike go left. Still the bike went right but not as much. By the way the motorway was fairly empty and I didn't let it steer very far.
So maybe those racers do know what they are talking about. Maybe I need to see a video of the no BS bike with a rider standing on one peg for a sustained period, not bouncing on it very briefly.
Thoughts?

He doesn't seem to be holding on at all???
I must be looking at this in the wrong way somehow.
-
All I can think of is his arms but all the advice I've heard tells me thats wrong. He's at the front of World Supersports races though and that Spies fella isn't bad either???
-
Hi all,
Watching the World Supersport race this weekend I saw Anthony West "wave" is right leg as an apology to Cal Crutchlow on the way out of a left hander. He was still leant over a long way at the time. He can't be locking his leg into the tank if he can do that so how is he holding himself on the bike? After seeing that I noticed that Ben Spies and many others were not locking their outside legs into the bike at all. Any ideas?
-
My real test is if I'm able to roll off the throttle to maintain my line.
Roll off to maintain your line? Huh?
Again, I know this isn't good practice or technique, but it seems to be something which happens to me at one point or another during a track day.Actually, it's called a survival reaction, not a technique. And it's a bad deal because it makes the bike run wide.
I know that its correct that rolling off the throttle will not tighten the line but at a recent track day I was running wide on a very tight turn, rolled off the throttle (unthinking survival reaction) and the bike tightened its line. It did, I know it shouldn't but it did and no I didn't adjust the steering, not conciously anyway. How is this explained.

Hi all,
Did you all see Lorenzo's highside in practise? It looked very much to me like he turned in too quick though Keith says this shouldn't happen?
Any ideas?
I'd post a link to the video but it has been taken off all the video sites I know, not sure why.

Thanks for that but I am a bit more concerned with the back. Does anyone know how much more grippy a medium would be?
