Re: Steer Clear - understanding steering for twinshocks

The explanation of the loop factor did effectively loop my brain. I do have a reasonable mathematical ability, but I'm sure I'll need to read it at least 5 more times before there is a chance that I may "unloop" I dip my helmet to JC1. So here is the question that I've needed resolved and...

Re: Steer Clear - understanding steering for twinshocks

. It’s worth looking into this ‘loop factor’ in a little more depth. It’s a bit of a sidetrack but it does affect steering to some degree (under power). The natural tendency of a vehicle under acceleration is to ‘squat down’ on the rear suspension due partly to the change in weight distribution sin...

Re: Basket Cases

I haven't found a photo of any custard tarts yet but did stumble across this interesting looking :suzuki . Photo taken at the 2008 Qld Titles That RL looks quite nice in orange and black. Nice wrap-around bash plate too. Brent, you mentioned (in another thread) about modifying RLs in NZ back in the...

Re: Results give motivation

The things that give you motivation. Hopefully the parts I'm fitting now won't have to come back off until after it's been running and I decide to tidy it up. Wasn't sure about the position of the rear guard at first but it allows full travel and it's starting to grow on me. I'm so tempted to take ...

Re: Basket Cases

Brent, I just went back to p228 and the pics of your bike and you are correct in thinking they are not RL forks on it. The RL sliders are quite different shape at the bottom, above and below the axle. Also RL forks have the oil drain screw at the back not the side and do not have a lug on LH slider ...

Re: Steer Clear - understanding steering for twinshocks

Good point about the KT's forward weight bias. Again, the problem seems to be when laden. If my data is correct unladen specs for the KT (44/56%) are very similar to other twinshocks (TY250 45/55; RL 46/54; 240 Fantic 46/54; SWM Jumbo 44.5/55.5), but footpeg location is considerably more forward tha...

Re: Steer Clear - understanding steering for twinshocks

I'm glad you found it useful. All thanks to Tony Foale and his book, who also kindly gave permission to use his diagrams. I had to read some sections of his book n times too before I fully got it. But it's so enlightening when you do. With the KT, in search of more trail, it might first be worth loo...

Re: Basket Cases

Has the rake been pulled in too David, or am I just imagining it ?
Or is it just the effect of the raised rear end?
