losing the back under front braking...sometimes?

[Val]

Hello guys,

I wonder if there is something wrong with my front brake. Under hard front brake braking (not emergency hard) my back end starts twitching.

I mean even it is not that hard, way way softer then doing stoppies for example. My back wheel is on the ground but I feel I am losing it.

Happened few times in the last week. Once was I needed to shave off some speed to get in a queue I was overtaking and the back started to go hard left and right. I was thinking that is because I was close to the centre paint line maybe the paint was the reason.

Then it hapenned few times in the middle of the lane too under hard front brake braking (not emergency hard), even not that hard lets say ambitious front brake braking.

Any ideas? I don't have ABS. Never happened to me with the Fazer. I know MT09 is lighter, still doesn't feels right. Obviously I have adjusted my riding, but modern bikes are supposed to brake very well. That reminds me 30 years ago with the drum brakes. Forward planing was the key  :lol

Anyhow not happy to have fast bike that can't stop well. What is wrong?
