hi ross,you are correct in that the steering angle has been tightened up, but the swinger is standard, just with the wheel as far forward as it will go. the history of this bike is that it was a farm bike, and got run over by a tractor....so was pretty bent when i got it. so it seemed that while i was straightening out the frame, i might as well tweek it to make it into a trials bike.i'm very pleased with the result , not sure what the weight is but it's quite light and very usable. did it's first trial a couple of weeks ago (classic/ post classic)and performed well.....and was great fun.
here's a few pics from the cust reunion trial.
