Please excuse any non biker terminology Mr. Green in fact replace it with the correct terms if you like Mr. Green
Before I passed my DAS test I had a 125cc. On my 125 when entering a corner I could literally 'push' it deeper into a corner by transferring my weight over the left/right side of the front wheel. It was quite easy to do and you could use it to correct any number of evils. The same I recall would happen going downhill but I'd somehow transfer that weight distribution to the back wheel by somehow pushing my back and butt cheek over to the left or right Mr. Green It was a subtle move btw it wasn't like I was showing someone my ass Mr. Green
However on my Fazer 600 it pretty much ignores any attempts at this and that flexibilty I had on the 125 seems gone. So now I enter a corner at speed and it seems I just lean over now which seems pretty one dimensional and not right.
Erm what am I missing Question Mr. Green

Leaning over is the only way you'll get the bike to turn. By moving your weight to the inside of the turn, you are altering the centre of gravity so you need less lean angle at a given speed to make the turn. With a light bike, your body mass has more of a significant role in altering the centre of gravity, meaning shifting your weight around will make the bike seem easier to turn than on a heavier bike.

Don't forget your 600 is a lot heavier than the 125.

Are you counter steering?

Yeah you will find on a 125 if it was a small bike handling would have been so much lighter, on 600's if you lean a lot use the throttle to bring you back up on the exit.

If your going into a corner with a bike that weights around the 200 kilo mark, it will need a some stern counter steer, and shift your weigh in the direction of the turn. Youll be surprised how far it will lean.

Bare in mind the Fazer has also got steering geometry to cope with 120mph plus top speeds, so it would turn in slower even if it wsa only 120kg.

Yeah I realised that but if I alter the front shock settings form standard will that make any difference to the turn in? Yeah I do counter steer all the time. You do it even without realising I guess.

Ahh so coming out of the corner if you don't increase the throttle you could potentially end up on your ass? Interesting. A mate of mine who passed at the same time as me came off his bike when taking a corner at speed a few weeks ago. Said he couldn't "get back up" on exiting the corner. I've not had any kind of experience like that so couldn't understand what had happened.

So thats it by the sounds of things. I'll miss the added bit of control I seemed to have on the 125 but glad it's been explained to me.

Changing the shock settings will alter how the bike turns in, but another way is to increase the rear ride height. You can also bring the forks through the yokes a little further. This should quicken up the steering at the expense of stability.

I was just wondering how the bike styles compared, sport, commuter, etc. The weight will definitely make a difference as well as things like suspension setup, tyres, riding style, etc.

You will be able to man handle the Fazer more but it's comes with practise and confidence, basically learning how and what you can get away with.

Sports bikes are actually harder to ride fast, at least at moderate sppeeds, than roadster style bikes (bandit etc) untill you can get used to their geometry.

Sharp geometry and clip ons make them harder to shift around, but this is the price you pay to get stable handling at 120mph+

Supermotos etc all are easier to throw about but are not the most pleasant things flat out.

You need to sit the bike up and get on the throttle as soon as possible, usually after the apex. Obviously using some discretion so not as to highside Wink
