Im not sure how many riders out there do there provisional on a long wheelbase 500cc+ bike. but looking at the test below. i cant justify why the cones activity is "irrespective of engine capacity" where you see the U-turn alters a difference of 600mm. clearly stating that the cornering is alot harder. now i turned up to my course today quite confident and was able to do everything that was put in front of me, but when they set up the spacing of the condes with the 0.6m offset the 250's were going fine, i am on a yamaha Fz6r which is a reasonably long wheel base 600cc.i also weigh around 60kg. when i attempted the cones the first time i had only JUST made it without touching anything. And the U-Turn was done without hesitation. after the 250's went through and knocked the couple cones over they were moved back into position. attempted again i steering locked while going around each of these cones to discover my rear wheel was hitting the one i had just past on each individual one. My rant is that clearly the U-turn is marked wider for 500cc+ as it has a larger turning circle etc so that would be the reason why i am having so much trouble with this. i have spent the whole day practicing and had no problem getting everything right except that. What is your opinion? has many other people had trouble with this? http://www.stayupright.com.au/pdf/MOST_ACT.pdf- Page 5 of 7 this activity is located on.
