DescriptionThe whole story▼
For riders who demand genuine race-derived suspension on the Yamaha YZF-R3, the K-Tech RAZOR-R LITE shock absorber delivers track-focused performance at an accessible price point. Built around an internal reservoir design that physically separates nitrogen gas from damping oil, this unit maintains consistent, fade-free damping lap after lap — whether you are pushing hard on circuit or threading through technical road sections.
Key Features
- Internal reservoir separates nitrogen gas from damping oil, eliminating aeration and guaranteeing consistent damping performance across extended sessions
- 16-way adjustable rebound damping allows precise tuning to circuit conditions, tyre compound and rider preference
- Adjustable spring preload accommodates a wide range of rider weights and riding styles without compromising base setup
- Length adjustment optimises ride height and chassis geometry for improved corner entry and mid-corner stability
- Nitrogen (N2) charge at 15.00 bar prevents foaming and sustains repeatable damping characteristics throughout a race or track day
- Direct OEM replacement fitment — no modifications required for installation on 2015-2026 YZF-R3
- Multiple spring rate options available to match exact rider weight requirements
Race-Derived Engineering for the Street and Track
The RAZOR-R LITE is the entry point into K-Tech's proven RAZOR range, carrying the same engineering philosophy as units found on professional competition machines. The 35.00 mm diameter body houses a 14.00 mm shaft, giving a rigid, precise action that translates directly into improved traction and chassis control. The 48.00 mm stroke and 160.00 N spring rate have been selected specifically for the YZF-R3 platform, working in concert with the 46-150 series spring to provide a balanced, responsive ride on both smooth circuits and uneven road surfaces.
An overall length of 276.00 mm with a tolerance window of -4 mm to +6 mm and 3.00 mm of RCU adjustment range gives the suspension tuner meaningful scope to dial in ride height without resorting to aftermarket linkage components. The upper eye mount measures 35.00 mm wide with a 12.00 mm bolt diameter; the lower eye mount is 60.00 mm wide with a 12.00 mm bolt diameter — both machined for an exact, rattle-free fit in the standard YZF-R3 mounting points.
Setting Up for Maximum Performance
The 16 clicks of rebound adjustment and 10 mm of preload adjustment provide a meaningful tuning envelope for track days and club racing alike. Start with the baseline settings recommended by K-Tech for the R3, then fine-tune rebound to control chassis pitch under braking and corner exit. Preload adjustment allows the sag to be set correctly for rider weight, which has a direct impact on steering geometry and front-to-rear balance. Installation must be carried out by an authorised K-Tech Service Centre — specialist tools and expertise are required to ensure full performance and safety.
