Good find. To be honest, I'll take something over nothing as long as it doesn't look too garish. May give this a shot though; I'll be sure to share if I do. Bit pricey; would jump at say $150-175 but @ $369... bit steep. http://www.nitronracingshocks.com/TOBY-STEERING-DAMPER-Triumph_p_2496.html
I suppose it is better than nothing, but also thinking static might have advantages? Careful on fitment. I have a 2019 RS, but they do list up to 2018 on Toby site, 2017 on Nitron site. Hoping to get confirmation on fitment soon.
Had a Toby damper on my Speed RS for the track, just as insurance really, but it didn't really need it. You can just see it in the pic. If anyone wants the damper it's in the for sale area, only done one trackday https://www.thetriumphforum.com/threads/speed-triple-rs-toby-steering-damper.22305/
Did the damper hinder turning radius of the bike? The tolerance looks tight left to right on the damper bar.
Matris now makes a mounting kit for the 2016-2020 Speedy. It uses a fork clamp, and is placed under the headlamps. They offer a static pressure damper and a dynamic. Pricey! Over $600 US.
