I'm in the process of drawing the leading legs conversion for my VL1500/Dnepr sidecar. In deciding on trail reduction I began to wonder about the effect of the 1500's chopperesque steering head angle. As a solo the thing has real enthusiasm for going straight on in any corner- needing muscular counter steering to deflect it from its course. This is I think the combined effect of its humungous 300kg weight and considerable wheelbase as well. What is the effect of this angle when going round a corner upright though? I'm guessing its long wheelbase and rearward weight distribution means, like old Harleys apparently, I can get away with less sidecar wheel lead? I'm thinking 15% max. I am struggling though to get my head around the amount of trail reduction, and whether there's any significant interaction with the steering head angle. I'm a fairly small older guy and I don't want too much of a workout when I'm out riding. It's all twisties around here! Is the steering head angle not relevant with an outfit- we all know it makes a tremendous difference to a solo- it's why a Ducati is so much fun, and why I'm putting a third wheel on the Suzuki!
