The Teknik 59-225 rear shock spring range is designed for KTM motorcycles using WP XPLOR, XACT and PDS rear suspension systems requiring a 59 mm internal diameter and 225 mm free length spring. Manufactured in Europe exclusively to Teknik Motorsport specifications under ISO 9001 certified production processes, these springs are available in both linear and progressive configurations to suit different rider preferences, terrain types and suspension setups.

Why Choose a Teknik 59-225 Shock Spring?

The OEM WP spring range is relatively limited in available rates and is primarily supplied in linear configurations. The Teknik 59-225 range was developed to extend beyond the standard WP offerings, providing additional lighter and heavier spring options as well as progressive-rate alternatives for riders looking for different chassis behaviour and suspension feel.

Linear springs maintain a constant rate throughout the suspension stroke and are often preferred by experienced racers and aggressive riders because they hold the rear of the motorcycle higher in the travel and provide a more direct and predictable chassis response.

Progressive springs increase in rate deeper into the stroke, giving a more compliant initial feel while increasing support during larger impacts and acceleration loads. Many recreational riders and club-level racers prefer progressive springs because they can improve comfort and traction in rough terrain while still maintaining good bottoming resistance.

Neither design is universally “better” — rider preference, terrain, speed and suspension setup all influence which spring characteristic works best.
