DescriptionThe whole story▼
Built for the sharp end of the grid, the K-Tech TRDS-R rear shock delivers championship-grade suspension performance on the Kawasaki ZX-10R and ZX-10R RR across the 2016 to 2026 model range. The 'R' in TRDS-R stands for Regulation — a design philosophy that enables ultra-precise setup changes to extract lap-time gains within the tightest cost-cap racing environments, from club-level competition right through to British Superbike and the Isle of Man TT.
Key Features
- Through-Rod (TRDS) technology provides exceptional sensitivity and tunability, allowing riders and engineers to monitor and dial in chassis behaviour with pinpoint accuracy.
- Compact, reservoir-free design improves heat dissipation and delivers consistent damping performance across extended race distances — no fade, no compromise late in a stint.
- 18-click compression and 18-click rebound adjustment (recommended baseline) give a wide, finely graduated tuning range to suit every circuit and riding style.
- Developed specifically for teams working within championship price restrictions, maximising outright performance without demanding unlimited sponsorship budgets.
- 45 mm RCPU body diameter with a 14 mm rod ensures structural rigidity and reliable operation under sustained race loads.
- Race-proven at the highest levels: series-specification choice for British Superbike competitors and Isle of Man TT runners.
Through-Rod Technology Explained
Where a conventional shock uses a hollow damper rod, K-Tech's Through-Rod design runs a solid rod through the full length of the damper cartridge. The result is a more direct, linear relationship between wheel movement and damping force — the kind of transparency that lets a good engineer read the data and make meaningful suspension changes between sessions. Combined with the reservoir-free housing, heat generated under race conditions is managed more efficiently, keeping oil viscosity stable and damping curves predictable from the first lap to the last.
Designed for Regulated Racing
Modern superbike championships impose strict cost controls that can limit which components a team may use or how much they can spend. The TRDS-R was engineered as a direct answer to that challenge. It sits within common regulatory price brackets while offering the same quality of information and adjustment range as uncapped race hardware. Teams running limited budgets and reduced technical support can still arrive at every round with a shock that genuinely responds to setup work — a meaningful competitive advantage when sponsorship is tight and every session counts.
