Tuning Chain & Sprocket Kit for Suzuki DR 600 S-SU SN41A (1985–1989)
A worn drivetrain set on the Suzuki DR 600 often causes rough chain movement, imprecise power transmission and increased wear on the gearbox output shaft and swingarm components. This reinforced tuning chain kit for model SN41A is specifically designed for production years 1985–1989 and features a modified gear ratio with 15 teeth at the front and 42 teeth at the rear. This shorter gearing improves acceleration while slightly reducing top speed, making it particularly suitable for riders who prioritize stronger pull in lower and mid RPM ranges.

Technical Specifications of the Drive Kit
Shorter Gear Ratio for Improved Acceleration
-
Front sprocket: 15 teeth, reinforced version
-
Rear sprocket: 42 teeth, reinforced version
-
Gear configuration: Shorter ratio compared to OEM setup for quicker throttle response
-
Chain: Gold-colored X-ring chain, double reinforced
The 15/42 tooth configuration increases rear wheel torque delivery, resulting in noticeably faster acceleration and improved responsiveness, especially in off-road sections or technical terrain. Riders who frequently ask how to achieve stronger pull at lower speeds benefit directly from this gearing modification. The trade-off is a slightly reduced maximum top speed due to higher engine RPM at cruising speeds.
Double Reinforced X-Ring Chain Technology
The integrated X-ring sealing system minimizes friction and effectively retains lubrication between pin and bushing. This design offers:
- Reduced wear under high load conditions
- Improved sealing compared to conventional O-ring chains
- Stable power transmission even during aggressive acceleration
- Extended service intervals due to optimized lubrication retention
If your current chain shows elongation, uneven tension or vibration under load, replacing the complete drivetrain set ensures balanced wear distribution and smoother operation.
Motorsport-Inspired Manufacturing Technology
Diamond-Cut Tooth Profile for Precision Operation
The sprockets are manufactured using an advanced Diamond-Cut process developed in cooperation with the University of Paderborn. Compared to conventional milled sprockets, this method achieves a significantly higher dimensional accuracy.
- Optimized tooth geometry for smooth chain engagement
- Roundness and flatness tolerances below 0.1 mm
- Improved concentricity for vibration-reduced drivetrain behavior
- Reduced point loading on individual chain links
Precise manufacturing is particularly important when modifying the gear ratio, as higher torque loads require stable and dimensionally accurate components.
High-Strength Steel Qste 420 / Qste 460
The rear sprocket is manufactured from high-grade structural steels Qste 420 or Qste 460. These materials provide high tensile strength combined with durability under continuous dynamic stress.
- CNC-machined center bore for accurate fitment
- Precisely countersunk and deburred mounting holes
- High structural stability under heavy acceleration loads
- German brand manufacturing – Made in Germany
Practical Benefits in Real-World Riding
A worn or incorrectly matched chain kit commonly leads to:
- Irregular throttle response
- Chain vibration and noise
- Increased wear on transmission components
- Inconsistent rear wheel torque delivery
By replacing all relevant drivetrain components as a complete kit, you ensure uniform wear patterns between chain and sprockets. The reinforced 15T front sprocket combined with the 42T rear sprocket enhances low-end torque response, making long off-road sections and technical trails more controlled and responsive.
