Compare the RAM Multi-Pad Yoke Clamp and Handlebar U-Bolt mounts: rail size limits, mounting surfaces, and which notepad setup fits your vehicle or handlebars.
Quick answer
Choose the RAM Multi-Pad with Yoke Clamp Mount if you need to clamp onto a rail or tube from 0.625" to 1.25" in diameter, such as an aircraft yoke or similar rail. Choose the RAM Multi-Pad Mount with Handlebar U-Bolt Base if you are mounting to a handlebar or round bar where a U-bolt wrap is the better physical fit; its catalog entry does not state a diameter range, so verify your bar size before ordering.
Why the clamp style matters more than the pad
Both products use the same RAM Multi-Pad document holder, so the notepad, pen magnet, and spring clip experience is essentially the same. The real decision is the base: a yoke clamp tightens around a rail with a 90-degree jaw, while a handlebar U-bolt wraps around a round bar. That difference determines which vehicles and bars you can actually attach to, and how much room the mount takes up.
The yoke clamp's published 0.625" to 1.25" range is the clearest fit specification between the two. The handlebar U-bolt listing does not provide a comparable diameter range, so treat it as a fit-to-be-verified item rather than a universal bar mount.
The trade-off: known range vs. handlebar-specific wrap
The yoke clamp gives you a documented rail range and a compact 90-degree profile that suits yokes and similar rails. The handlebar U-bolt is shaped for handlebars and round bars, which can be an advantage on tubular bars where a wrap-style base seats more naturally, but you lose the published diameter range as a selection tool.
If your bar diameter is outside 0.625" to 1.25", neither listing guarantees a fit from the supplied facts. In that case, measure your bar and confirm compatibility before purchase rather than assuming either base will clamp safely.
Decision rules for choosing between the two bases
- If you are mounting to a yoke or rail: Measure the rail diameter. If it falls between 0.625" and 1.25", the RAM Multi-Pad with Yoke Clamp Mount is the documented fit. A rail outside that range is not covered by the supplied specification.
- If you are mounting to a handlebar or round bar: The Handlebar U-Bolt Base is shaped for this surface, but confirm your bar diameter against the product before ordering because no range is listed. Do not assume the U-bolt fits every handlebar size.
- If you want the same notepad holder either way: Both mounts use the RAM Multi-Pad with spring clip, 5" notepad slot, and pen magnets, so base fit should drive the decision, not pad features. Pick the base first, then treat the pad as the constant.
Product facts
- RAM® Multi-Pad™ with Yoke Clamp Mount: The RAM-B-121-MP1U includes a 90-degree yoke clamp base that mounts to rails from 0.625" to 1.25" in diameter. This published range lets you check your rail size before ordering and is the main reason to pick this version for yoke or rail mounting.
RAM® Multi-Pad™ with Yoke Clamp Mount - RAM® Multi-Pad™ Mount with Handlebar U-Bolt Base: The RAM Multi-Pad Mount with Handlebar U-Bolt Base uses a U-bolt base and is described for car, truck, or plane use. The U-bolt wrap suits handlebar and round-bar mounting, but the listing does not state a diameter range, so bar size must be confirmed separately.

Which mount fits your setup?
Best for
- Riders or pilots mounting to a rail or tube within 0.625" to 1.25" in diameter
- Users who want a published rail-size range before buying
Not for
- Handlebar owners who have not confirmed their bar diameter against the U-bolt base
- Rails outside the yoke clamp's stated 0.625" to 1.25" range
