【2-Way Grip Heaters / Coaxial Type】
High-output 45W grip heaters. Supports two installation methods: reusing the stock throttle cone or using the included throttle cone. Comes with spacers to adjust grip and bar-end cap lengths. Designed for easy installation on motorcycles with a standard 22mm handlebar diameter and grip lengths of 115mm, 120mm, 125mm, or 130mm. Features a 33.5mm outer diameter, close to the feel of stock grips. The clutch-side grip can be secured with a set screw. All components, including connectors and the controller, are IP67 waterproof, making them suitable for bikes with exposed harnesses like naked or cruiser models. The remote control resumes the operating state from before the ignition was turned off, and the output mode increases with each button press. The coaxial controller features a USB Type-C port supporting 5V3A/9V3A/12V2.5A fast charging. *If a device not compatible with fast charging is connected, the protection circuit may activate and prevent charging.
【Installation Instructions by Grip Length】
■ 115mm: As the grip is 120mm long, it will protrude 5mm outward on the throttle side. On the clutch side, it will protrude 15mm due to the 10mm controller. For bikes with bar-end caps, use the included bar-end spacers (three 5mm pieces on the left, one 5mm piece on the right).
● The left side will be 10mm longer than the right side.
■ 120mm: Can be installed on the throttle side without spacers. On the clutch side, the grip end will protrude 10mm outward due to the 10mm controller. For bikes with bar-end caps, use two 5mm bar-end spacers on the left.
● To make the left and right lengths even, install two of the included 5mm grip spacers inside the throttle-side grip. In this case, use a total of four 5mm bar-end spacers (two on each side).
■ 125mm: As the grip is 120mm long, the throttle-side handlebar will protrude 5mm outward. Install one 5mm grip spacer inside the throttle-side grip. On the clutch side, the grip end will protrude 5mm outward due to the 10mm controller. For bikes with bar-end caps, use one 5mm bar-end spacer on the left.
● To make the left and right lengths even, install two of the included 5mm grip spacers inside the throttle-side grip. In this case, use a total of two 5mm bar-end spacers (one on each side).
■ 130mm: As the grip is 120mm long, the throttle-side handlebar will protrude 10mm outward. Install two 5mm grip spacers inside the throttle-side grip. The clutch side can be installed without spacers.
* The clutch-side grip will protrude 10mm outward due to the 10mm controller. If you wish to equalize the left and right lengths, please use the grip spacers.
If the bar-end cap interferes with throttle operation, use the included 1.5mm bar-end spacers for installation.
* For models without bar-end caps, please use the included end caps.
* Please determine changes to handlebar end length according to safety standards at your own responsibility.
【Throttle Installation Methods】
■ Electronic Throttle: Remove the stock throttle cone, smooth out any protrusions on the cone surface using a disc grinder or similar, and insert it into the product's grip. Bond the grip and throttle cone using grip heater adhesive. If using grip spacers, insert the spacer between the throttle cone and the grip beforehand.
■ If the stock and included throttle cones are identical in shape: Confirm that the included throttle cone rotates smoothly within the throttle housing, then insert it into the product's grip. Insert the throttle cone end from the outside of the grip. Bond the grip, throttle cone, and throttle cone end using grip heater adhesive.
■ If the stock throttle cone shape is different: Remove the stock throttle cone, smooth out any protrusions on the surface using a disc grinder or similar, and insert it into the product's grip. Bond the grip and throttle cone using grip heater adhesive. If using grip spacers, insert the spacer between the throttle cone and the grip beforehand.

What is a product defect?
A product defect is a malfunction which can be restored to the original specifications of the product by repair or replacement. However, cases where the product specifications (specs, functions) do not meet the user's requirements are not considered product defects.
What is an initial defect?
If a malfunction occurs due to defects caused by individual differences in materials or manufacturing during normal use within 6 months of purchase, and the symptoms can be clearly confirmed in advance with images or videos, it may be considered a manufacturing defect, and we will first mail a replacement product free of charge. After receiving the product, you will use the return envelope enclosed and return it to us for inspection. If the product is not found to be defective upon inspection, we will replace it for a fee. Even if it is within 6 months, depending on the product and the state of damage, it may not be considered a manufacturing defect. We will handle it as a manufacturer's warranty, not as a manufacturing defect.
What is a manufacturer's warranty?
If a breakdown or other problem occurs during normal use due to defects caused by individual differences in materials or manufacturing, etc., we will repair or replace the product free of charge within the warranty period set for each product (including shipping costs for repair or replacement). The purpose is to protect customers from damage caused by damage to products that would not normally be damaged due to individual differences in the product. In addition, the purpose is to understand the product-specific defects and characteristics that are discovered through actual use, and use this information to improve the quality of products that we plan in the future.
Warranty period
The warranty period is from the date of purchase to the date stated in the product information. If the warranty period has expired, repairs or replacements will be available for a fee. For products that cannot be repaired or replaced, please purchase a new product.
