Well folks, had my very first proper tankslapper yesterday. Unfotunetly never managed to rescue it.
Both my and bike are mostly ok.

Having just exited a roundabout in Dundee, there is a sweeping right hander leading onto the Riverside. Having just came round this corner the rear end slid out; which I managed to correct. But as soon as the rear came back in the bike stood straight up and started going lock to lock. Not really sure what happened next but after about the 6th set of lock to lock the bike spat me off. Cue me and bike skidding down the road.

My foot had become pinned under the bike, some bloke came running over and lifted it off while we got it into the layby which I had just about reached along the floor! Couple of folks stopped and were really helpful. I took a bit to check over myself, thankfully was wearing all my kit. My boot is worn straight through and theres a small scuff on my trousers but other than that; completely unscathed. The bike is almost as unharmed as me. The useless mirror took some of the impact (bin job) the front brake lever has seen better days, rear brake lever bent, scratches on exhaust guard. Pretty light too

The front pistons were pushed back in the callipers so the slapper must have been reasonably violent.
Im thankful that things werent worse and thanks to the car drivers who stopped to help me out!

Looking back at the corner theres a drain cover that is completely slick just about where I lost traction - combined with the wet weather yesterday could explain alot. Poor observation on my part.

Anyone else had the dreaded slapper?

Sounds like you were lucky (as in damage wise).

Well done to all that helped and stopped. Karma

Nope not had that happen yet, touch wood. Only been riding bigger bikes a short time.. Must have shit you right up. They say you should power out of it but I bet power is the last thing you think of when the bike is trying to buck you off.

Good to hear that you were ok though.

I once had severe tankslapper coming out of a bend down the Snake Pass towards Glossop on an old, steel pedal bike at 40mph (wearing just a pair of lycra shorts and a cycling jersey).

I almost shat myself and I thought I was going to be off.

Braking made it worse and I ended up riding into a grass bank to stop.

Was my hornet 600. Quite suprising - however I think it was the rear end slide rather than raw power etc.

Back end stepped out, then you went into a tank slapper, then you and the bike parted company.

That happened to me at my last session at mallory park. I lost the rear end at gerards bend (fast right) and shut the throttle off. It gripped and threw me onto the tank. It then went into the most violent tank slapper I have ever had. Luckily as I wasn't holding the bars it sorted itself out.

I finished that lap and went and had lunch/ changed my pants Thumbs Up

I caught a potential highside on my 'Blade and then it turned immediately into a tankslapper that threw me off.

Same thing happened to one of the WSB boys at Monza at the weekend didn't it ? I think it was one of the Leon's. Back stepped out and nearly highsided before he caught it and that in turn caused the front end to shake pretty violently. I wouldn't have wanted to be the one who had to wash down his leathers afterwards Thumbs Up

Tank Splappers should be banned in my opinion.
They're no use to anyone.

i suppose the act of catching it and the rear suddenly gripping making the front light could cause a slapper especially at a sudden lean angle.

twas just the 'back end sliding then tank slapper' that confused me. the point where grip came back wasnt mentioned.

pretty good going to manage that on a hairnet tho

From original post:

Quote:
the rear end slid out; which I managed to correct.


Sorry, probably wasnt clear. When i say "Managed to correct" I meant to imply that the rear regained traction and was back in line with the rest of the bike ( I assume!)

Quote:

From an 86(claimed)Bhp machine. Not all that unreasonable.
In saying that though I was nowhere near rolling on any sizeable amount of power, seemed more to me like a pure conflict of forces.

Not something im looking forward to ever repeating.

I had my first serious one the other day taking an uphill corner at speed and hit some pot holes / damaged road and the front just shook violently side to side. I thought I was coming off and it happened so quickly and was over quickly.
