So my RC51 is new to me.

I havent noticed any mechanical issues, it was owned by an Acura/Honda mechanic prior to my purchase.

When i move the bike when it is not running it makes a click noise and slight vibration in the handlebars... its not a consistent noise, its like clockwork on every revolution of the wheel. The werid thing is when i apply the brakes, even slightly (without it actually engaging) the noise goes away.

It also occurs when the bike is running but i can not typically hear it when moving because the bike is so loud. i could hear it when coasting in neutral down my work parking lot today. CLick Click CLick ... like clockwork unless i apply the brakes. I'm worried because like the rest of you i like to ride in triple digits and dont want my bike falling apart on me when im flying down the highway.

does anyone else have this noise occuring, or know how to fix it? Is it a problem that needs fixed? I wish i knew more but cant tell if its a normal thing or not. let me know your thoughts

Maybe grit and glazing on the rotors/pads or warped disk. Try cleaning the rotors, pads, and calipers.

Caliper bolts tight and everything?

Is your front tire wearing evenly?

I'll have to check them when i get home. tire looks to wear evenly, i could be wrong.. i'll be proping her up and taking tools to her to make sure everythings tight. But it's so weird because there is absolutely no sound when the brakes are even slightly pressed.

That is wierd, try doing the above and let me know if it helps at all. I can't think of anything else it could be at the moment.

Do you have one pad that is worn more than the other?
If so, you have may a dirty caliper piston that is not retracting properly.

now that i think of it, brakes squeak when stopping. What is recommended when it comes to brakes? just a new set of pads? which are the best or most commonly used by rc51 riders?

Galfer..EBC are good enough for street. Do you have a gauge and gauge block to check the run out of your discs?

Also, check and make sure your forks are level (Upper lower triples tight??), I have seen where this has caused some unusual front end noise too.

Worse case, I would pull the wheel and reinstall it after checking the brakes.

May want to check the steering head bearings too. If these have never been lubricated/changed, they may be due.

Also, around the time you replace the pads, with old pads removed, use an old toothbrush with soap and water and scrub around the caliper piston area to remove dirt and brake dust.
It will make the pistons operate better in their bores and improve brake operation.

An other wild guess? I've seen this before and it came from the pads. Some cheap pads that were painted with some kind of coating, thick like plastic, on the sides/profile area of the pad and as the pads wore out a bit the paint got cooked and started peeling off and was ticking (click click?) against the vents of the rotor. If you take them out and just cut that flaky paint off they will be fine, if not glazed themselves as cheap pads do.

Runout check on both rotors with the bendable gold colored carrier attached. I once bent one after installing VFR tires at home.
Remove brake pads and then use cardboard to limit piston travel to the removed brake pads including the rotor thickness, extend the pistons all the way out using the brake lever.
Liberal use of brake cleaning fluid and soft tootbrush over the exposed caliper pistons will do away with any potential sticking.
Lube caliper pins.

I had the exact same problem on my GSXR 600. I removed the pads and caliper, sprayed off everything with brake clean. Greased the pad slides and caliper slides. Used some light grit sandpaper on the pads to remove any glaze. Noise was gone. What was happening to it was the pad was sticking a bit on one side and not returning to its rest position away from the rotor. So every time the rotor (which was slightly warped) came around to that one spot... made a noise.
