Description
The Rolon Brass Chain & Sprocket Kit for KTM Adventure 390 is a complete stock-spec drivetrain replacement designed specifically for the KTM Adventure 390. This kit includes a brass-coated drive chain along with matching front and rear sprockets. It is supplied as a matched set so all drivetrain components wear together evenly. This ensures consistent performance and long-term reliability.
Replacing only the chain or only the sprockets can cause premature wear. Worn sprockets can damage a new chain quickly. A stretched chain can accelerate sprocket tooth wear. The Rolon Brass Chain & Sprocket Kit for KTM Adventure 390 eliminates that mismatch by replacing the entire drivetrain contact system at once.
Designed as a Direct Replacement
This kit is engineered to match the KTM Adventure 390’s original factory drivetrain dimensions. It maintains the stock chain pitch, width, and tooth count. No gearing ratio changes are introduced. Wheel alignment and swingarm geometry remain unchanged.
The Rolon Brass Chain & Sprocket Kit for KTM Adventure 390 is not a performance ratio upgrade. It is a stock-spec replacement solution. That means installation does not require modifications or recalibration. It restores factory riding characteristics without altering power delivery behavior.
Brass-Coated Chain Construction
The drive chain in this kit features brass-coated outer plates. The brass coating provides an additional surface layer that helps improve corrosion resistance in varied riding environments. This is especially relevant for motorcycles used in touring, rain exposure, or dusty road conditions.
Internally, the chain uses hardened steel pins, rollers, and bushings. These components handle load transfer from the engine to the rear wheel. The brass finish is applied externally and does not change the internal mechanical strength. It adds durability while maintaining stock fitment specifications.
Regular cleaning and lubrication remain essential. Even brass-coated chains require periodic maintenance to protect internal moving parts.
Matched Steel Sprockets
The kit includes both front and rear sprockets manufactured to KTM Adventure 390 factory specifications. The front sprocket fits directly onto the gearbox output shaft. The rear sprocket mounts to the original rear hub bolt pattern without modification.
Tooth profiles are precision-machined to match the supplied chain. Proper pitch engagement reduces uneven load distribution. This supports smoother throttle response and stable power transfer.
Because the sprockets are designed to work with the included chain, drivetrain wear is distributed evenly across all contact surfaces.
Why Replace as a Complete Kit
Drivetrain components wear together as a system. When one part degrades, it affects the others. Installing a new chain on worn sprockets can cause accelerated elongation. Installing new sprockets with an old chain can cause premature tooth wear.
The Rolon Brass Chain & Sprocket Kit for KTM Adventure 390 solves this by refreshing the entire system. All engagement surfaces begin their wear cycle together. This helps extend service life under normal riding conditions.
Real-World Use Suitability
This kit is suitable for:
• Daily commuting
• Long-distance touring
• Mixed on-road use
• Light adventure riding
• Standard maintenance replacement
It is not marketed as a racing chain conversion. It does not alter final drive ratios. It is intended to restore original drivetrain condition when the stock setup has reached its wear limit.
Installation & Service Notes
Installation requires removal of the existing chain and sprockets. Proper torque specifications must be followed for the front sprocket nut and rear sprocket bolts. After installation, chain slack must be adjusted to KTM factory recommendations.
Improper chain tension can cause premature wear or drivetrain stress. Post-installation inspection after initial riding is recommended. Chain lubrication should be maintained at regular service intervals.
Professional installation is advised for riders unfamiliar with drivetrain servicing.
