Okay, so yesterday it was extremely unseasonably warm here in New York. It was 62 degress to be exact ! It was great, myself and 8 other buddies all got together and went screaming all over the city. We definately painted the town red. At one point I was following my buddy who's got a sick hayabusa with a custom orange paint job (beautiful bike !). Anyway, he decided to take a sharp right turn when i wasnt expecting it. I hammered on the brakes just before entering the turn. As I leaned into the turn I was still a little too hot to make it so I banged on the rear brake. This was only my third time riding this bike ('04 CBR 600rr) due to crappy winter weather. After banging on the rear brake it clanked about 5 times, click-click-click. It sounded and felt just like an ABS system. Does my bike have an ABS system or is something not right? Like i said I have limited expereince on this bike so far, due to inability to ride much because of the weather. Am I crazy ? Does my bike have ABS ? Is something loose/busted ? Help !?

You definitely don't have ABS on the RR.
Did you try to duplicate what happened?
Maybe rear wheel lock & hop?

I very seldom use rear brake.

XLSR954 is right, you do not have an ABS system. You might have created a little bit of wheel hop but very unlikely. Not sure that there is anything wrong with your bike. I would check the tension on your chain. If it is really loose it could of smacked on the swing arm. Learn to use your front brake more than anything or a smooth combination of the front and rear brake. Plus, try to give yourself plenty of room from your buddies to brake and turn.

It really didn't feel like tire lock & hop. It sounded like clanking. Since you mentioned the chain I do recall it sounding like the chain. I'm not sure, it was a weird situation I was in. I have tried jamming on the rear brake but I can't reproduce what happened. Thanks for your help guys and I will definately check that chain out.

the guys are correct. You dont have any kind of abs system, but this could be from very new disk plate and new tires. (you write that you have driven the bike for a ltitle period, so i assume that everything is brand new!)

Could be back torque limiter on the clutch -- designed to keep you from locking the rear wheel when downshifting hard but can act sorta goofy when getting on the brake hard.

Yes, the bike is brand new. I've been able to ride it 3 times since I bought it. The bike had nothing on it for mileage, it now has just over 250 miles. The incident happened around 210 miles or so. I did check the chain and all seems fine, it has between .5" - .75" of play, which I consider just fine. Must be the newness of it all, not quite broken in yet. I'll be bringing it to the shop where I bought it for the 600 mile check-up and I'll be sure to mention it. Oh hey, one more thing since I'm thinking about it. I went to check out the contents of the toolkit. There's a spot for putting the key in. Well for some reason the key doesn't seem to work ! It wont go in all the way and will not turn. Am I crazy ?

.5" to .75" of slack in chain is not enough -- your chain will die prematurely. Trust me on this one -- I've busted more than my fair share of chains. Give that bad boy at least an inch.

Is your toolkit under the rear seat like the 1000RR's? If the key won't open it up take it to the dealer and make 'em fix it while the weather sux. You can also pick their brain about the clicking when hard braking.

I am going to say it was wheel hop/transmission chatter from the abrupt use...I dont think you hurt anything

Thanks for all your help and suggestions guys.

no anti-lock breaks...most likely and nearly only possiblity is wheel chatter/hop...also happens when you downshift in high rpm's without pre revving the motor


chainstretcher...do the bikes already have the back torque limiters on them...i wasn't sure if they were starting to be released with this technology yet or not...i haven't read many new or recent motorcycle magazines yet...i know that bmw is starting to release it in their new M series sport touring cars


idealy this would reduce the need to pre rev the motor while down shifting and reduce/eliminate rear wheel chatter under deceleration...all be it more wear on the clutch pack

I think that they do have that. I know that my Busa did and it was an '01 -- Honda is usually about 5yrs ahead of everybody else techwise. Don't have the ability to downshift without revving - tried it a couple of times but my right hand betrays my brain. On the Busa I only did it a couple of times in emergency situations. Makes a Gawd-awful noise coming through the clutch.
