Answers to the most common fit questions about the RAM Tough-Mirror Kit with M10-1.25 bases and M10-1.5 adapters, including thread sizing and long-arm placement.
Quick answer
The RAM Tough-Mirror Kit with M10-1.25 bases and M10-1.5 adapters fits motorcycles that use either common mirror thread size, so you can mount a mirror without guessing which pitch your bike has. The long arm adds reach for wider fairings or taller riders.
Why the kit includes two thread pitches
Motorcycle mirror mounts use two common M10 thread pitches: 1.25 mm and 1.5 mm. Rather than making you order the wrong base, this kit ships with M10-1.25 bases and M10-1.5 adapters. That means one box covers both standards, which is useful if you own more than one bike or plan to move the mirror between machines.
When the long arm helps and when it does not
The long arm gives you more clearance between the mirror and the handlebar, which can keep the mirror out of your line of sight or away from a tall windscreen. On a narrow bike with tight cockpit space, the extra length may put the mirror closer to your hand or levers. Check the space around your existing mirror before committing to the long arm.
Frequently asked questions
- Which mirror thread size does my bike use?
- Check the base of your existing mirror stalk or the threaded hole in the perch. M10-1.25 and M10-1.5 are the two common pitches; the kit includes bases for 1.25 and adapters for 1.5. If you are unsure, test-fit the base by hand before tightening. Hand-thread the base first to avoid cross-threading.
- Do I need the M10-1.5 adapter?
- Only if your mirror mount uses the 1.5 mm pitch. The kit includes both, so you can keep the unused adapter for a second bike or future change.
- Will the long arm fit my handlebars?
- The long arm adds reach, so measure the gap between your mirror perch and the space you want the mirror to occupy. On bikes with narrow bars or handguards, the standard arm may be a better fit. Mock up the mirror position with the arm before final tightening.
- Can I use this kit on a scooter or e-bike?
- The kit is designed for motorcycle mirror mounts with M10 threads. Scooters and e-bikes often use different thread sizes or clamp-on mirrors, so check your mount type before ordering.
