Showa's new revolutionary Triple Air Chamber Fork (TAC) is now being offered as an upgrade to customers who already have Pro Circuit's SFF Air Suspension kits. In 2014, factory teams such as Team Kawasaki, Suzuki, Honda, RCH and TwoTwo Motorsports have already been using the third air chamber with success, and now you can add this beneficial part to your suspension kit.


The concept behind the Triple Air Chamber is simple, the third chamber, with its own oil volume, replaces the negative spring (balance spring), and the parts it takes to hold that spring in place. The idea of a negative spring is to hold the air fork to a certain length, or in other words, it gives air a length. A stiffer negative spring, or more pressure in the third chamber, would be like running less preload in a normal set of spring forks. A lighter negative spring, or less pressure in the third chamber, would be like running more preload in a normal set of spring forks.


There are three benefits to upgrading to the TAC fork: One, going stiffer or softer on the balance spring is now done externally with an easy air pressure adjustment. Two, the transition point of engagement and disengagement of the balance spring is eliminated, which means a smoother and seamless stroke. Third, adding or taking oil out of the third chamber makes the return stroke much more progressive, and adjusting the progressiveness of the return stroke can now be done externally as well, a performance advantage that no other fork has to offer.


The new Triple Air Chamber fork (TAC) is truly state of the art. Every aspect of what is required from a set of forks can now be controlled and adjusted externally from just the TAC fork itself. The ride height, initial plushness, overall stiffness and the rate of progression from the compression and rebound stroke can all be adjusted with the TAC fork.


The Works shock features race-inspired details to provide a distinct advantage over OEM shocks. The giant 18mm shock shaft comes standard with an extra-large 16mm diameter piston holder, housing the bigger check valve system for more oil control, isolating the compression and rebound stroke and also adding more piston and shim stability. These features result in a more stable and controlled ride with slightly cooler temperatures. The 50mm hard-anodized Kashima coated body has less friction and reduced heat build up. For maximum performance and adjustability, the compression assembly separates high and low speed valving circuits and adjusters.

The all new 2013 Works Showa Suspension by Pro Circuit is designed for the rider who demands the most in both performance and appearance of their suspension. Ever detail has been refined to create the first 100% complete Works Suspension kit that doesn't compromise anything. Both forks and shock are hand assembled with Pro Circuit's internal specifications and spring rates, tailored to meet your personal racing needs.


For 2013, we are introducing Showa's all new revolutionary Works SFF (Serparate Function Fork) Air Fork. These forks are a huge step forward in technology, with exclusive state of the art designs providing damping and spring functions (Air) in separate fork legs, opening up several performance advantages. Since the left fork has no spring; the cartridge, pistons and shims are a lot bigger, providing better front end traction, bump absorption and a much more comfortable stroke with less feedback. The right fork houses two air chambers, each having their own oil volume. The inside chamber (high pressure), and outside chamber (low pressure) can both be adjusted by changing the pressure and oil volume to achieve the type of performance you require. Since the damping tasks are taken care of in the left fork, heat build up on the air side is minimal and pressure will stay consistent. Friction is reduced by 25% and overall weight is substantially reduced (in most cases over 2 pounds). The forks still feature big 49mm titanium nitrate coated tubes that provide more durability along with a smoother stroke. The larger internal cartridge system is larger; Kashima coated, sealed and pressurized much like a shock. With larger CNC-Machined billet axle lugs and a shorter redesigned outer fork tube, the flex balance is greatly improved.


The Works shock features race-inspired details to provide a distinct advantage over OEM shocks. The giant 18mm shock shaft comes standard with an extra-large 16mm diameter piston holder, housing the bigger check valve system for more oil control, isolating the compression and rebound stroke and also adding more piston and shim stability.
