G+Note Belt Drive Aluminum Sprocket Kit for GROM125 (5-Speed: JC92)

G+Note Belt Drive Aluminum Sprocket Kit for GROM125 (5-Speed: JC92) Applicable model year: JC92 Belt: GATES brand (Shipping included/tax excluded) The G+Note Belt Drive Kit for GROM125 is an extremely rare and rational custom package that replaces the motorcycle's "chain" drive with a "belt" drive. It offers mechanical beauty and an overwhelmingly "silky" riding experience. Three advantages that will change the common perception of drive systems 1. Surprisingly "quiet and smooth" acceleration The characteristic "chattering" metallic sound of a chain and the jerky feeling during acceleration and deceleration are eliminated. The unique elasticity of the belt drive gently transmits the engine's pulsations to the tires, transforming the riding feel into a high-quality, silky experience, as if riding a luxurious electric motorcycle. 2. The freedom of "maintenance-free" You are freed from the "regular cleaning" and "lubrication" essential for chains. No dirty hands: Since no oil is used, the area around the rear wheel will not be stained with splattered grease. No adjustment needed: Since the belt hardly stretches like a metal chain, frequent tension adjustments are unnecessary. The belt is a high-performance brand made by GATES, used in Harley-Davidson and other vehicles. 3. The "pulley" as a sculptural beauty The large aluminum machined pulley (gear) is a precise work of art in itself. Especially when the sprocket cover is removed, the sight of the belt rotating smoothly is the ultimate in **"functional beauty"** for mechanics enthusiasts. It adds a modern and clean accent to the Monkey's retro appearance. It is lighter compared to a chain set of equivalent strength. The use of aluminum sprockets further reduces weight this time. *About adjusting belt tension Initial adjustment is important for belt drives. Slack can lead to breakage or shorten the belt's lifespan. Tension gauge Measured by the "deflection amount" when a load of approximately 4.5kg (10 pounds) is applied. 目安のたわみ量：8mm 〜 14mm (Estimated deflection: 8mm to 14mm) Simple "finger measurement" without a tension gauge It is difficult to apply an accurate 4.5kg load, but judge by the feel when pressing firmly with the pad of your finger. Measurement guide: Press down firmly on the midpoint of the upper and lower spans of the belt with your thumb. Typically, there should be enough slack for "the first joint of your thumb to sink slightly (approx. 10mm to 15mm)". "Too tight" signs: If it barely moves when pressed with a finger, or if it's so hard it hurts your finger, it's too tight. This can damage bearings and cause a "whirring" noise during driving. "Too loose" signs: If it lifts off the pulley teeth with a light push of a finger, or if the belt ripples, it will "skip" during acceleration/deceleration and damage the belt. The secret to extending belt life is to adjust it so it's not "drum-tight" at its tightest point. Regarding the belt The belt used is a durable GATES product. If not properly set, or depending on road conditions, external pressure, and other usage methods, premature damage may occur. If any abnormalities (cracks, damage, defects) are found before installation, we will replace it, so please contact us without installing it. Once installed, it is considered to have passed inspection, and under no circumstances will it be covered by warranty. Also, performance is not guaranteed indefinitely. If wear, damage, or abnormalities are found on the belt, please replace it with a new belt immediately. Purchasing implies acceptance of the above conditions. The maintenance method for Harley-Davidson's belt drive is essentially the same, so please refer to it. Drive Belt Maintenance Method
