Have questions about fitment, installation, shipping, warranty, or orders?
The OFFRAMP team is here to help.
Before reaching out, you may find the answer you need in the knowledge base below.
The OFFRAMP Internal Throttle Kit is designed for standard 1-inch handlebar ends. It also fits most custom oversized handlebars, as many “fat bar” setups still use a 1-inch control-end tube.
Please note: fitment is determined by the diameter of the handlebar end, not the main body of the handlebar.
No. The OFFRAMP Internal Throttle Kit is designed for cable-operated throttle systems, not throttle-by-wire systems.
However, because the internal mechanism is built around modern grip dimensions, this kit requires a TBW-style throttle grip or throttle tube to work properly.
Yes, in many cases. As long as the motorcycle uses a cable-operated throttle system and has a compatible 1-inch handlebar end, the OFFRAMP Internal Throttle Kit can be used for custom builds outside Harley-Davidson applications.
We always recommend confirming your handlebar size and throttle setup before installation.
Yes. Most non-TBW motorcycles have used push-pull dual-cable throttle systems for decades. However, the return cable is not the main force that closes the throttle. On a properly set up carburetor or throttle body, the return spring is what pulls the throttle blade back to the closed position.
The OFFRAMP Internal Throttle Kit is designed with an internal return spring. In real-world custom builds, many of our internal throttle kits are installed on motorcycles that originally came with dual-cable throttle systems.
No welding is required, and you do not need to shorten the handlebar.
Installation only requires cutting small locating slots at the end of the handlebar. These slots help lock the internal throttle tube in place and prevent the whole mechanism from rotating when the throttle is twisted.
This can usually be done with a rotary tool, die grinder, or small hand file.
You may use a TBW-style throttle housing to secure the grip at the handlebar end. OFFRAMP also offers dedicated mounting components designed specifically for our Internal Throttle Kit.
These parts help secure the internal throttle assembly firmly in place, giving your custom build a clean, stable, and reliable throttle setup.
Most OFFRAMP product pages include installation resources such as PDF guides or video links. Our YouTube channel also features installation videos to walk you through the process.

We currently accept PayPal as our primary online payment method.
No. OFFRAMP discounts and promotions cannot be stacked.
Our system will automatically apply the best available price based on your current membership status, dealer status, or active discount eligibility.
PayPal checkout issues may be related to the browser environment used to open the payment page. In some cases, when the website is opened through an in-app browser from a social media platform, PayPal may not correctly recognize the shipping address or checkout session. This can cause delivery or payment errors.
We recommend opening the OFFRAMP website directly in Chrome, Safari, Edge, or another standard browser, then returning to the checkout page. Enter your shipping address on our website first, confirm that shipping rates display correctly, and then choose PayPal to complete payment.
For a more stable checkout experience, you may also use a desktop or laptop computer to place the order.
