K&N Motorcycle Oil Filter KN-204-1 — High-Flow Synthetic Media with Wrench-Off Nut

The K&N KN-204-1 motorcycle oil filter is a high-flow, heavy-duty replacement filter with premium synthetic media and an integrated wrench-off nut for fast, reliable oil changes.

Designed for modern sport, touring and adventure bikes, this K&N Performance Oil Filter balances filtration efficiency with unrestricted oil flow to protect engines while accommodating long service intervals. Built from rugged materials and engineered to work with synthetic and conventional oils, the KN-204-1 is made as a direct-fit replacement for a wide range of Honda, Triumph and Yamaha models. Its welded nut speeds removal, and internal valves are tuned for application-specific pressure control.

How does this filter improve engine protection without restricting oil flow?

The KN-204-1 uses premium synthetic filter media arranged in uniform pleats to trap contaminants while preserving oil circulation. That combination yields high dirt-holding capacity and reduced pressure drop so lubrication reaches critical parts quickly.

• High-efficiency synthetic media for fine particle capture
• Uniform pleat geometry to maximize surface area and flow
• Laboratory-tested capacity and burst strength for durability

Can this filter handle extended mileage and synthetic oils?

K&N engineered this filter for long service life and compatibility with premium synthetic, conventional, and blended oils. The design includes a part-number-specific bypass/pressure relief valve to maintain proper lubrication under different oil types and conditions.

• Rated for extended protection—designed to support long drain intervals
• Optimized for synthetic motor oils and high-temperature use
• Internal pressure relief to prevent oil starvation in cold starts or heavy loads

What makes installation and removal easier for riders?

The KN-204-1 features an integrated, welded wrench-off nut that lets you use a standard socket or wrench, eliminating the need for a separate strap or cap tool. The filter is built as a direct replacement where applicable, so fitment and swapping are straightforward during routine maintenance.

• Welded nut allows quick removal with common tools
• Application-specific dimensions match factory fit where required
• Durable construction resists damage during service

Which motorcycles is this filter compatible with?

The KN-204-1 covers many contemporary Honda, Triumph and Yamaha two-wheelers, from naked bikes and cruisers to sport and adventure models. Always verify compatibility against your bike’s year and model, but this part supports a broad cross-section of popular machines.

• Fits multiple Honda models including CB, CBR, GL1800 Gold Wing, and Forza ranges
• Compatible with numerous Triumph Bonneville, Tiger, Street Triple and Rocket models
• Also fits Yamaha models such as MT-03, MT-07, Tenere 700 and Tracer series
