Well … given the opportunity:
- Google Honda ProLink and ProArm: The mother of modern swingarm suspension concepts started back in 81 (Honda XR) and carried over via the notorious RC211V and the CBR1000RR (aka Blade).
- What are these? These are linkage systems that allow a progressive compression. This plays a paramount role in the way that the shock delivers the goods and justifies the hi-low compression and rebound adjustments in any given shock (plus preload).
- Now … a top shock for a proper sports motorcycle is a 1.5K - 3K thingy (Ohlins TTX36, WP 4618, Showa Racing, Penske custom etc etc) … meaning that bicycles can’t affort them (say an Ohlins TTX22). Meaning that the more the suspension allows the shock to work properly the more a cheapo shock can deliver. That said Ducati did a BIG mistake in the Panigale V2 (using a direct linkage): the mass production big piston Showa used in my ProArm Blade (shock mounted in the swingarm) eats the whole Italian thingy for breakfast.
- All that were sci-fi for bicycles in the past. But these days … they start to catch up with progressive suspensions as well.
BTW: Added a ProLink system (“like a PL” in fact with regard the EXACT motion of linkage B … but GH is NOT CATIA you know).

Study what’s happening and see why Honda is Honda (and the rest are just motorcycle makers).
