DescriptionThe whole story▼
Fork seals that fit perfectly and last the distance make every ride more confident — whether you are threading through mountain passes or returning from a track day. The K-Tech DSS-013 Dust Seals Kit is manufactured by NOK, one of the most respected seal producers in motorsport, and is dimensioned to drop straight into the MV Agusta F3 675 and F3 800 (2012–2026) with no modification required. The result is a fork that stays smooth, stays clean and keeps feeling exactly as it should across thousands of kilometres.
Key Features
- Precise OEM-dimension fit — engineered specifically for the MV Agusta F3 675/800 (2012–2026), making installation straightforward and eliminating the risk of incorrect sizing.
- Manufactured by NOK — a globally recognised name in sealing technology, synonymous with consistent material quality and long service life.
- Comprehensive environmental protection — the seals form a reliable barrier against road grit, trail dust and moisture that would otherwise attack the fork stanchions and oil seals beneath.
- Extended suspension service intervals — by keeping contamination out, the dust seals reduce wear on the oil seals and fork internals, preserving smooth, precise damping for longer.
- Kit format — two dust seals supplied together so both fork legs are refreshed simultaneously for balanced performance.
Build Quality and Performance
NOK's compound formulation maintains its flexibility and sealing lip geometry under the thermal cycling and mechanical flex that motorcycle forks generate in everyday use. The dual-diameter stepped profile — 54.20 mm outer diameter at the lower shoulder and 59.80 mm at the upper register — locates the seal correctly in the fork leg and prevents rotation or walk during operation. At 43.00 mm inner diameter the seal fits the F3's stanchion tube without pinching, so fork action remains fluid rather than notchy. The 6.00 mm and 11.00 mm height dimensions mirror the original specification, meaning no reshimming or adjustment is needed at installation.
Fitment and Compatibility
This kit is compatible exclusively with the following models:
- MV Agusta F3 675 (2012–2026)
- MV Agusta F3 800 (2012–2026)
Installation requires specialist tools and correct technique to achieve the seating depth and alignment that guarantee performance and safety. K-Tech recommends that the work is carried out by an authorised K-Tech Service Centre or a qualified suspension technician.
