Motorcycle Shock Gas Bladder & Cap Upgrade Kits
When most riders talk performance the first thing they think of is POWER - but if you're smart, that's the last on the list. Shoving grunt into a chassis that can't cope builds a scary bucking bronco. First steps are basics - make sure your bike is properly maintained, clean, no leaks, fresh oil, good clutch setup. Remove any extra weight. Fit grippy tyres. You've got the perfect starting point! Quality suspension comes next & Teknik Motorsport are motorcycle suspension tuning experts.
Piggyback rear shock absorbers have a reservoir attached to the side, pumped up with nitrogen, absorbing small initial bumps. Internal Floating Pistons can be used to separate the suspension fluid & air pressure - but are complex & can leak. So many bike manufacturers use thick durable rubber bladders inside, like a heavy duty industrial party balloon. The factory bladders, end caps & gassing ports can be improved using these quality aftermarket replacement parts though.
Sick of leaky, inconsistent IFP dampening? Try a smooth, reliable DIY bladder internal conversion kit. More plushness & comfort? A high capacity bladder cap or larger canister sets increase gas volume inside the damper - in colourful anodized aluminium alloy. Need tyre clearance? Low-profile flat or angled head end caps can fine tune that. Is refilling your shocks a pain? Swapping between a schrader valve & a needle type port means you have different regassing tool options.
