EXCEPTIONAL RESPONSIVENESS.
Ultimate Suspension Tuning Pro-level CMX (Compact Motocross Tune) damping with fully tunable compression and rebound circuits with high-flow internals that stay cool and consistent. R38 shares the same high-flow base valve cavity architecture as the larger R46. Massive oil flow delivers true moto-level damping feel, control, and consistency normally reserved for full-size motocross suspension.
TUNING WITHOUT COMPROMISE.
2SC (Two Stage Compression) Hard-hit capability meets unmatched ride feel. Built to handle the biggest impacts with greater control and stability while preserving the smooth, connected ride feel Sirris is known for. Features independent high-speed and low-speed adjustability:
-
Tool-free low-speed compression adjust, 18 clicks
-
High-speed compression adjust, 24 clicks (20 mm hex)
-
Tool-free rebound adjust, 24 clicks
Made For You Tunable to any rider style and condition. Personalize to your rider weight with high-tensile steel spring rate options: Medium (63–81 kg = 90 N/mm spring) and Heavy (81–100 kg = 100 N/mm spring). (Note: Listed weight ranges are rider weight without riding gear on).
BUILT TO LAST.
High Durability Finishing Features a massive 16 mm induction heat-treated hollow shaft with a hard chrome finish—delivering extreme structural strength and huge oil flow. Constructed with CNC 6061 billet aluminum, type 3 hard anodized coatings, and a proprietary internal floating piston system to manage shaft displacement under high heat loads.
Extremely Easy to Rebuild Fully serviceable true powersports architecture ensures easy rebuilds and custom tuning.
Required Linkage Upgrade To accommodate the massive shock for smaller bikes, Sirris teamed up with Prickly to develop an R38 specific linkage. Note: You Need the PRICKLY LINKAGE for the R38 Shock. The stock E-Ride Pro linkage WILL NOT WORK with the new R38 shock. 289 mm length (78 mm stroke).
Lightweight Weighs only 1.5 kg without spring.
