13 inch progressive install

[Ishrub]

They shouldn't be on the softest setting. They should be on the right setting.

Look up how to set up motorcycle sag properly, there is an actual procedure for dialing in shocks.

If you leave them on the softest, they'll bottom out, and then they'll bounce off the rubber stopper and it will be a hideous pogo stick, not a shock. Try winding them up to at least 50% preload. And are these normal Progressives or the Heavy Duty model? They recommend the HD for guys over 270 lbs or for two-up riding. If they're not HD, wind them to 75% preload or more, especially two-up, or get HD ones.

225lb not 270lb.

Note: Standard Duty shocks are for ride loads under 225 lbs., Heavy Duty shocks are for ride loads regularly over 225 lbs.

225lb not 270lb.

Right, my bad, remembered that one wrong. But the Rocket itself is also quite a hefty bike with a fair amount of sprung weight, so HD for these would probably make sense unless you're a featherweight.

The Progressive web site says: "444 Series shocks are available in 3 configurations: Standard (Up to 250 lbs.), Heavy-duty (250+ lbs.) and Super Heavy Duty (Touring Models only - 350+ lbs.)."

But I think the 444-4221C are the HD model, so that should be fine.

Bonjours à tous. Je trouve intéressant vos commentaires sur la suspension. Les routes par ici demandent presque que de rouler en moto d'Aventure, mon autre moto étant une R1200GS (BMW). Mais j'aime bien rouler ma Rocket 3 (2006) aussi, avec mes amis en Harley, et j'ai des limites d'endurance au dos. Donc je crois pouvoir améliorer le confort de ma R3 en changeant les amortisseurs arrières. Quelqu'un a déjà essayé ces modèles, amortisseurs " Progressive Suspension serie 412", je pèse 200lbs et ma conjointe embarque à l'occasion :Progressive Suspension 412 Series Shocks - 412-4012C
