G+Note Belt Drive Aluminum Sprocket Kit for Honda Monkey 125 (5-speed models: JB03 / JB05)

"Silence and silky acceleration, free from lubrication." From metal chain to high-durability reinforced belt system. A custom kit that brings a completely new riding pleasure to the Monkey 125.

This is the "G+Note Belt Drive Custom Kit" designed exclusively for the Honda Monkey 125 (5-speed models: JB03 / JB05). By replacing the conventional metal drive chain with a high-durability reinforced cogged belt system made by the world-renowned belt manufacturer GATES, it achieves astonishing quietness and a silky smooth, direct acceleration feeling.

Four Innovative Values Provided by Belt Drive Conversion

1. Say Goodbye to Oil Stains. Completely "Maintenance-Free"

   • No need for troublesome cleaning or lubrication: Tedious regular lubrication and greasy dirt removal with chain cleaner, common with metal chains, are now a thing of the past.
   • Always keep your undercarriage clean: The complete elimination of scattered chain oil allows you to maintain the rear wheel and swingarm area in a consistently beautiful and clean condition.

2. "Overwhelming Quietness" to Enjoy the Engine's Original Pulse and Exhaust Sound

   • Completely eliminate friction noise: Thoroughly eliminate the clanking and friction noises unique to metal chains during riding. You can enjoy the exhaust sound of the Monkey 125's muffler and the comfortable original pulse of the engine more clearly.

3. "Silky Acceleration Feeling" You Can't Go Back From Once You Experience It

   • Flexible torque transmission: The moderate flexibility unique to belts dramatically alleviates the jerky shock during gear changes. Experience seamless, smooth, and direct riding, from low-speed city cruising to high-speed touring.

4. Rust-Resistant, Combining "Lightweight" Undercarriage with "Long Lifespan"

   • Rust-free high-precision sprocket: Adopts high-precision aluminum sprockets and reinforced belts that are completely free from rust concerns. Being overwhelmingly lighter than metal chains, unsprung weight is significantly reduced, making the rear suspension's movement even more supple.

Frequently Asked Questions (FAQ) & Initial Adjustment

Q. Can I easily install it myself? A. While it is a bolt-on design, the "initial tension adjustment" of a belt drive greatly affects the product's lifespan and performance. To ensure a safe and enjoyable riding experience, we strongly recommend having the work performed by a professional motorcycle shop or dealer.

Q. Does it stretch like a chain? Is frequent tension adjustment necessary? A. Because it uses special reinforced material, the initial "stretch" is extremely small compared to metal. Once set to the appropriate tension, frequent fine adjustments are not necessary afterward.

【Important】Belt Tension Adjustment Guidelines:

• When using a tension gauge: The deflection should be 8mm to 14mm when a load of approximately 4.5kg (10 pounds) is applied.
• Simple measurement with a finger (guideline): When pressing down firmly on the center of the belt with the pad of your finger, a deflection where "your thumb's first joint sinks slightly (10mm to 15mm)" is typical.
  • *Too tight: May cause a "whirring" noise during riding and damage bearings, etc.
  • *Too loose: May cause "tooth skipping" during acceleration/deceleration and lead to belt damage.
