The fastest I have travelled on my motor bikes was 150 MPH (KPH is a foreign language to me!) on my 1992 Honda CBR 600FM on the M5 Motorway between Gloucester and Exeter in 1993.
Gave it a try to see what it was like.
Trying to steer around a very gradual bend in the motorway and avoid the approaching barriers was difficult!
Sorry, your Honour....Never again!....

Nowadays, speed scares me!
