"This is a story about bike control. Do you think you can manage incidents when you drive? This guy can. During the last weekend in february 2015 Speed Weekend was arranged in Årsunda Sweden. The purpose of the event is to drive fast on ice, similar to Bonneville in USA but on ice and with shorter tracks. 1500 m acceleration, 1000 m speed measurement and about 1500 breaking.

This guy runs a Kawasaki ZZR1400 chip tuned and extended swing arm, might be more mods but no turbo. The tyres are normal class (W) high speed tyres or racing slicks with a high number of go-thru sharpened screws added.

The guy enters the first speed measurement at 281 kph (175 MPH) acceleration continues up to approx 320 kph (200 MPH) when the rear wheel suddenly looses grip and start to spin. This happens approx 200 m before the second and last speed measurement. A fraction of a second later the rear tire explodes and completely leaves the bike.

The situation now is 320 kph (200 MPH) speed on wet ice and no rear tire. Rear end friction is litterly zero. And what is the guy doing? He front brake as hard as he can and unload the rear wheel almost completely. A few seconds later he passes the second speed measurement at 293 kph (182 MPH) more or less on the front wheel. As speed goes down he can release some of the front brake power and eventually stops, still on the wheels. Please note that the speeds are real speeds recorded by electronic timing equipment.
Ohh I almost forgot to tell that this guy is 72 years old, his name is Örjan Jonsson and his nic name even before this incident was grandpa of steel.

This run was the fastest bike run during the entire event, several of his competitors had turbo bikes with for sure twice his horsepower.

Rose is interested in a picture of the Plymouth Satelite, if you have one.  Those are fast speeds.  Very impressive.  What is the density altitude there?

That one caught my eye as well.

Any pics you could post up would be welcome.

Thanks!

Speaking of SpeedWeekend on Ice -- take a look at the home page of landracing.com.  I thought that Anders might deserve a bit of extra recognition.  Thanks to Bob for putting it up there.

Perhaps he didnt have very good ice tyres, he seemed to be struggling to get set away from the slushy start line on Friday afternoon, from what i saw

loads of pictures coming soon from Mark Thomas on the photos section
