b40rt Posted August 20, 2013 Report Share Posted August 20, 2013 What's considered to be a good compromise angle for steering angle ? Currently about 23 degrees. Thanks Quote Link to comment Share on other sites More sharing options...
pschrauber Posted August 20, 2013 Report Share Posted August 20, 2013 There once was a good article about steering angles and frame dimensions in German Trialsport. The article is already a couple of years old but it was considered that an angle of 73° would be fine. See in your personal messenger.

b40rt Posted August 20, 2013 Author Report Share Posted August 20, 2013 (edited) Thanks Patrik The info in your drawing would equate to an angle of 17 degrees measured at the top. Makes mine look quite "relaxed" Edited August 20, 2013 by b40rt Quote Link to comment Share on other sites More sharing options...
neil01 Posted November 27, 2015 Report Share Posted November 27, 2015 Hi all, has this info been shared anywhere? I would be interested in having a look, if I could, please. Thanks Neil Quote Link to comment Share on other sites More sharing options...
b40rt Posted November 27, 2015 Author Report Share Posted November 27, 2015 Steepen head angle by 1.5 degrees, or get longer shocks, or drop forks buy 25mm. Quote Link to comment Share on other sites More sharing options...
neil01 Posted November 27, 2015 Report Share Posted November 27, 2015 Thanks, that was quick! 1.5 deg doesn't sound much but I don't know the effect of a small change like that; did you end up doing it, and if so, did it make a discernible difference? I might just lift the back end with some longer shocks, as they need replacing anyway. I always think they look better lifted a bit at the back and it would keep the wheelbase original, I suppose.

b40rt Posted November 28, 2015 Author Report Share Posted November 28, 2015 1.5° will make an appreciable difference, any more and you start to have issues with clearance with exhaust / mudguard. 25hmmm longer shocks is supposed to equate to 1°. Some makes of shocks you can be lengthen, 395mm is about max before the chain starts to hit the lower part of the frame, and the brake pedal. The brake pedal can be moved down if the footrests have been moved down and back. Where do you stop ? Quote Link to comment Share on other sites More sharing options...
woody Posted November 28, 2015 Report Share Posted November 28, 2015 Where do you stop ? My opinion only, but on an SWM there is no need to even start - those I've ridden are fine as they are and will steer around anything Altering steering on older bikes doesn't always give a benefit. I've a 340 Sherpa with altered steering and I'm not convinced. I'd guess there is a fine line between making something marginally better and ruining it 3 Quote Link to comment Share on other sites More sharing options...
neil01 Posted November 28, 2015 Report Share Posted November 28, 2015 Thanks guys. No substitute for experience. I've done the footrest position but I can put that back to standard if I want to in the future - the headstock would be a different matter and I think I'll leave it well alone. New shocks and see how it goes, then. Cheers Quote Link to comment Share on other sites More sharing options...
metisse Posted November 30, 2015 Report Share Posted November 30, 2015 I would agree with Woody, just changed the shocks on mine to 360 Rock shocks, great over the dry Spanish rocks this weekend, steering great, just got the clutch to fine tune.... somemore.....Patrik..

nigel dabster Posted January 1, 2017 Report Share Posted January 1, 2017 what trials are you intending to ride where changing the angle by 1.5 dgrees will save you marks? Practise for the time it takes to strip the bike pay for the work and youll probably end up better off marks wise? 1 Quote Link to comment Share on other sites More sharing options...
brownie001 Posted January 1, 2017 Report Share Posted January 1, 2017 Hi. Here's a pic of my modified TLNW320. It's also in the thread 'Show me your Twinshocker'. Anyway, the steering angle has not been modified. The pegs have been moved down and back, the bars have been raised and as you can see, the rearend has been lifted. The distance center to center of the rear shocks is now 375mm. It turns on a sixpence so I personally see no need to mod the steering angle drastically. Each to his own though. a mod which works for me, might not work for you and vice versa. I'm 1,83m and tip the scales kitted out at around 105Kg. The shocks are the latest on offer from NJB by the way, cost ca. €170. 1 Quote Link to comment Share on other sites More sharing options...
