K-Tech have released their popular 25SSK front fork open cartridge system to fit all Showa Big Piston Forks.

Here's what K-Tech have to say about them:

These lightweight aluminium units are supplied to the same exacting specification as all other 25SSK fitments with 14mm piston rods and a 25mm cartridge tube, the 14mm piston rods displace a large volume of oil through the 25mm control pistons giving enhanced damping characteristics over the standard Big Piston Fork and allow a bigger volume of air for a more precise feel at the bottom of the fork travel.

The cartridge kits have compression and rebound adjustment in both legs and are supplied with 1.5mm Flow Control Valves for a more accurate adjustment, all necessary hardware is supplied to convert the Big Piston Forks to take the cartridges but it is necessary to order the springs you require as these are not included, customer price for the 25SSK cartridges is £725.00 + VAT and are available for the following models:-


Honda CBR1000RR 2012
Kawasaki ZX6-R 2009-2012
Kawasaki ZX10-R 2011-2012
Suzuki GSXR600 2011-2012
Suzuki GSXR1000 2009-2012
