Mupo Custom - ST1 Shock and Falcon Cartridge

It is two years since Italian suspension specialist Mupo launched its Mupo Custom program, taking its race-bred street and sportsbike suspension experience and applying it to the handling and performance characteristics of heavier and less responsive Harleys.
In that time Mupo Custom has quickly established itself with a prominent reputation for premium H-D suspension solutions. 

ST1 shock

At the top of its Custom offer, the ST1 piggy-back style rear shock absorber (for pre-M8 Touring, Sportster, Dyna, V-Rod and Street 500/750 applications) features refined race-derived hydraulics and is available on request in various lengths from 11.5"(295 mm) to 15" (381 mm).
Mupo says that a pair of its ST1 shocks will improve control and comfort in all riding conditions - especially compared to stock shocks. Equipped with an external tank (piggyback) in steel, the ST1 shock absorbers are fully adjustable in compression, rebound and spring preload for optimal riding style settings and the wheelbase adjustment allows the rear axle to be raised or lowered, according to the driver's preferred riding position.
All components are entirely precision CNC-machined from high grade materials and the ST1 can be customized with red or black details/springs/body.

Falcon cartridge

They have a 14 mm stem, 35 mm piston, stem ΓΈ14 mm, an anti-cavitation separator piston between the nitrogen and 40 clicks of extension adjustment; 24 clicks of compression and spring load can be tuned in mm via the ring nuts.
Also seen here, Falcon 'Plug and Play' design front suspension cartridges (Softail, Dyna, V-Rod, XL) are equipped with compression, rebound and spring preload adjustments (40 clicks each of compression and extension), and feature a 22 mm aluminum cartridge, 22 mm sintered piston, 12 mm steel rod and chrome-silicon steel springs.
