Recommended Additional Upgrades
The RCB HG77 Rubber Handle Grip is often considered the more “aggressive” sibling to the HG66. It is designed for riders who want a firm, technical grip with a modern, sporty aesthetic.
While other grips focus on extreme softness, the HG77 is engineered for feedback and control, making it a favorite for sportbike and underbone riders who want to “feel” the front end of the bike more clearly.
Technical “Scale” Pattern
The standout feature of the HG77 is its unique Scale/Triangle pattern.
-
Directional Grip: The textured scales are designed to provide maximum resistance against the direction of your hand’s rotation. This means less effort is required to hold the throttle open, reducing “wrist pump” during long rides.
-
Deep Grooves: The deep channels between the patterns act as drainage paths, quickly moving water away from your palms during rainy conditions.
Slimmer Profile
The HG77 typically has a slightly slimmer outer diameter than the Nagamaki or HG55.
-
Who it’s for: Riders with smaller-to-medium hands or those who prefer a “closer” feel to the handlebar for precise inputs.
-
Material: It uses a high-density thermoplastic rubber that is slightly firmer than the HG66, offering better durability and a more “direct” mechanical connection to the bike.
Why Choose the HG77 over others?
-
The “Open-End” Convenience: The HG77 is ready to go if you have bar-end mirrors or weights. No messy cutting required.
-
Durability: The firmer rubber compound is more resistant to “tearing” or “crumbing” over time, especially if you ride with gloves that have aggressive palm protectors.
-
Sporty Cockpit: The design is very sharp and angular, which perfectly matches the aggressive lines of bikes like the Yamaha Sniper 155, Honda RS150R, or KTM Duke.
Installation Recommendation
Because the HG77 is a firmer grip, it can be a bit tighter to slide onto the throttle sleeve.
-
Pro-Tip: Use a quick spray of hairspray inside the grip. It acts as a lubricant while wet, allowing the grip to slide on easily, and then acts as a strong adhesive once it dries, preventing the grip from spinning.
