For the modern classic Speed Twin 900, new ready-to-fit suspension upgrades are available to enhance handling, performance, and riding comfort.
The M40TC-K and M40TD-S rear shock absorbers are available in either Dark or Chrome finishes, perfectly complementing the bike’s styling.
The premium M40TC twin-shock set offers full adjustment of compression damping, rebound damping, ride height, and spring preload.
The M40TD set provides adjustment of rebound damping, length (ride height), and spring preload.
Both kits are supplied with a dedicated spring preload adjustment tool.
For the front end, the high-performance 25 mm F25R and 20 mm F20K hydraulic cartridge kits feature the exclusive Quad Valve System, allowing full adjustment of compression damping, rebound damping, and preload.
These cartridge kits replace all original fork internals, require no modifications to the standard fork, and are supplied ready to install. They are also 100% reversible, allowing the motorcycle to be returned to its original configuration at any time.
A range of spring rates is available for both front and rear suspension systems, tailored to rider weight and intended use.
To complete the chassis setup, improve stability and safety during sporty riding, and reduce front-end vibrations, a steering damper based on the exclusive Speed Sensitive System technology is also available in SDR and SDK series versions.
Fully adjustable, hydraulically operated, and nitrogen gas pressurized, it is supplied with model-specific mounting brackets for a straightforward, ready-to-fit installation.
