[QUOTE="Little Honda, post: 26416, member: 667"] Hi all, I am worried about the flexibility of my roadholder forks. Mecanically, it is all done, no unwanted clearances, anywhere. But, if I take the frontwheel between my knees to keep the front wheel in position, it is possible to turn the handlebar by more than 1/2 in to both sides. Looking down the forklegs, it is clearly visible, how they twist. This weekend at the Schotten races, I did the same to the 2 present John Player Nortons, and another Manx in the paddocks: The same!!! This might be ok with a 120kgs racebike, but I wonder if it can do its job in a twin-norvin! Come-on, Norvinners, let me know your comments! I was worried to observe the same on famous racers and went to a 500 cc BMW racer with telescopic forks of the period. I know from my BMW days, that these forks are not the best, but I wanted a comparison. Result: They twisted much less than the roadholders! My forks have new stanchions, new precision-machined bushes to match my re-bored forklegs, and all screws are deadtight. :confused: [/QUOTE]
