RAM Motorcycle Brake/Clutch Reservoir Cover Mount with Diamond Base - Offset

RAM-B-183U Offset Reservoir Cover Double Ball Mount

The RAM-B-183U is a complete motorcycle mounting kit that fits over your existing brake or clutch reservoir cover, giving you an offset 1" B Size ball, a medium double socket arm and a diamond base adapter with the industry-standard 2-hole AMPS pattern. It is the tidy way to add a phone, GPS or action camera holder without giving up handlebar space.

Key Features

• Complete three-piece kit; nothing else to buy except your device holder
• Fits over the existing reservoir cover using the cover's own screw holes and longer screws
• Offset 1" ball shifts the mounting point clear of the reservoir so the device sits where you want it
• Diamond base carries the 2-hole AMPS pattern and accepts most RAM® holders and cradles
• Three sets of M4 screws (20mm, 30mm and 35mm) to suit different cover thicknesses
• Marine-grade aluminium with an over-moulded rubber ball
• Lifetime warranty

What's Included

• RAM-B-346U offset reservoir cover ball base
• RAM-B-201U medium double socket arm
• RAM-B-238U diamond ball base

Works With

Suits many road bikes from BMW, Honda, Suzuki, Yamaha, Kawasaki and Buell. The reservoir cap needs to be flat for a secure fit; some models with a rounded cap will not seat correctly, and this kit is not compatible with the 2016 BMW R1200RT. The diamond base accepts any 2-hole AMPS device holder. If you would rather buy the parts separately, see the RAM-B-346U offset base, RAM-B-201U medium arm and RAM-B-238U diamond base. For a centred ball rather than an offset one, look at the RAM-B-345U centred base, and if you need more or less reach you can swap the arm for the short or long B Series arm.

FAQs

Does this replace my reservoir cover? No. The plate sits above your existing cover and reuses the cover's own screw holes with the longer screws supplied, so the original cover stays where it is.

Will it fit my bike? Measure the two mounting holes on your reservoir cover. The centre slots are 61.9mm (2 7/16") apart and just under 12.7mm (0.5") long, so there is a little adjustment either way. The cap also needs to be flat rather than rounded. Not compatible with the 2016 BMW R1200RT.

What can I mount on it? Anything with the 2-hole AMPS pattern bolts straight to the diamond base, which covers most RAM® phone, GPS and action camera holders. Keep the total load under 907g (2 lbs).
