Ive never done something of these dimensions before and was wondering if anyone knows how I should set castor and camber angles up in this jig. The aforementioned dimensions are closet to a greenspeed GTR, altough a Greenspeed SLR was the inspiration for the wheelbase....thank god I had a tape measure on me
. The trikes purpose will b for racing, thus Im sure the castor should b pretty extreme....but Im assuming nothing
So, is there anyone out there who owns a greenspeed jig, a greenspeed trike, or a trike of similar dimensions at that, who can give me some advice? Help would b nice, and a link even better.
Thanx, Michael
I race fully faired trikes for 24 continuous hours here in oz. I have just built a trike which i think handles better than the SLR. It is 600mm wide and 1300mm wheelbase. I set the castor of the kingpins to 8 degrees from vertical leaning back at the top and the kingpin iclination must point the kingpin directly to the centre of the tyre contact point. This varies depends on the hubs used. We find that the trike handles better with the wheels leaning in (negative camber) at about 1 degree. Hope this helps
