DescriptionThe whole story▼
Keeping your Aprilia RS 660's front fork performing at its best doesn't require a full suspension rebuild. The K-Tech SBS-009 slide bushing kit is a straightforward, cost-effective maintenance solution that restores precise fork action on RS 660 models from 2020 to 2026 — made to exact OEM dimensions so fitment is never in question.
Key Features
- Hardened steel construction with a copper coating for long service life and reliable corrosion resistance
- PTFE-coated contact surfaces minimise friction, restoring the smooth and sensitive fork response the RS 660 is known for
- Machined to exact OEM dimensions — inner diameter 39.70 mm, outer diameter 41.70 mm, height 20.00 mm, wall thickness 1.00 mm — ensuring a direct, rattle-free fit
- Complete two-bushing set covers a full fork service in a single purchase
- A practical, affordable maintenance item that extends fork life and avoids costly premature wear to stanchions and seals
Build Quality
K-Tech's fork bushings are produced from hardened steel, then copper-coated to add a sacrificial layer that protects against corrosion and micro-scoring during normal use. The PTFE treatment on the sliding contact faces reduces static and dynamic friction, which is the primary cause of that characteristic fork stiction that blunts initial suspension response. The result is a fork that moves freely through its stroke from the very first millimetre of travel — valuable both on the morning commute and on a weekend trackday.
Everyday Usability
Worn fork bushings rarely announce themselves dramatically; instead you notice a gradual vagueness in front-end feel, increased stiction over small bumps, and eventually oil seal failures caused by the sloppy fit. Replacing bushings at regular service intervals with a quality item like the SBS-009 is far less expensive than replacing fork seals, wipers, or worse, refinishing scored stanchions. With accurate dimensions and a straightforward drop-in design, a competent technician can complete the job efficiently using standard fork service tooling — though K-Tech recommends the work be carried out by an authorised K-Tech service centre where specialist tools and expertise are available.
Fitment & Compatibility
The K-Tech SBS-009 is designed exclusively for the Aprilia RS 660 (2020–2026). It is not a universal part — do not fit to any other model or year range.
