Our Showa TAC Air to Spring Fork Conversion Kit is a complete replacement cartridge assembly for your current SHOWA TAC AIR Fork setup.  It is designed to completely remove all the Air system from your current Showa TAC Fork and replace it with a preload adjustable spring and cartridge setup.  

High Quality German Engineered ‘Eibach’ Springs are available to suit varying rider weights.  Please advise upon order or let us know your weight and speed  and we will recommend the best spring for you.

Spring Rate Recommendation

General riding & Motocross applications

These recommendations  are a guide only as fork Springs are weight and speed dependent. For example a 72 kg Pro rider falls into the 0.92kg/mm category but may well be better suited to a 0.96kg spring due to the much higher corner entry speed and the ability to hit large bumps at high speeds. Please note this guide is for rider weight ‘without’ gear.

Please note we have had great results using one spring down for Veteran/ C level riders on the 450 machines.  Eg. 90kg rider running a 0.96kg/mm spring for a plusher ride.

For more accurate advice please consult your local suspension tech or send us an email

Adjustable performance Linkage

Fits - Honda CRF450R 2021- Models 

Kit Includes:

• 2 x CRF450R Performance Linkage arms pre fitted with bearings and set to 0.5mm Option
• Optional 1mm interchangeable end buttons

Options included - 0.5mm (fitted) and 1mm interchangeable end buttons.  Resulting in +.5 or 1mm longer overall linkage pull arm lengths.  Our adjustable end buttons simply tap out and gently press in for an accurate setup.

Our adjustable linkage for the Honda CRF450R includes changeable rear end buttons allowing custom tuning of the 21/22 era Honda chassis to suit better rider balance.  Improved action under heavy breaking and more high-speed stability is achieved by lowering the rear slightly (as opposed to running excess suspension sag).  Utilising the linkage (either .5 or 1mm setting) in sandy conditions transforms the ride, reducing excess steer and allowing easier flow through fast whooped out turns.

We recommend our best tested 0.5mm button setting for most riders.  Using the 1mm button we have achieved great results with shorter riders and more stability especially in the deep sand conditions. 

Riders that like that low end flatter bike feel, less rise in the rear under braking and sand specialists will suit this performance linkage arm.
