Hey,

I've been riding for a year now on my 2006 CBR600RR, and I'm new to the forum. Recently a friend let their car roll into my parked bike (didn't set the e brake... duh!) and knocked it over on its right side. Damages are well over $3500 just from it hitting the ground. Long story short, I'm looking to do many of the repairs myself and make the insurance dollars stretch as far as possible.

First, I'm trying to replace both handlebars (the L bar was already broken). I see a lot of aftermarket clip on bars (as low as $15). I see in my Clymer manual that the CBR is equipped with inner and outer bar weights. I'm wondering (1) what I need to consider when looking at aftermarket clipons, (2) are the inner bar weights are really necessary (they look complicated), and (3) if the new clipons will permit the use of these bar weights.

Thanks.

I talked with the guys at the local bike shop and found out that the after market handle bars are not good. Stock handlebars have inner and outer bar weights to dampen vibrations from the engine and road. The after market bars don't accommodate the bar weights and apparently hurt like hell when you ride. They may be cheaper (or more expensive in some cases) but aren't worth it. The whole point of the after market clipons is to lighten the bike, which will work on the track, but not the highway. Conclusion: I'm going to stick with stock, cause I like my hands.

Yea and I'm sure you would hate tank slappers too. If you can keep the clip-ons stock I would do so.

There is nothing wrong with aftermarket clips. Be careful who you talk to as they don't always know the whole truth. Some clip ons allow for stock weights, some come with weights of their own, some do not allow for weights. It all depends on brand. Ones to look into, Graves, Vortex, Gilles, Harris. Price range for all is around $130 or less.

Really? Tank slappers have nothing to do with the amount of weight at the clips, the weight is just there to kill vibrations.

And what would happen if that vibration was to get out of control? The vibration would escalate eventually turning into a tank slapper. I'm in no way positive that it would infact cause one. I was just thinkin that if there was vibration that the possibility of a slapper would exist.

I'm talking side to side vibrations. There's a thing called resonance that could easily cause a very subtle vibration to get out of hand. Although, the possibilitys would be very slim, I think there might be a chance of it. Especially at a high rate of speed where other factors might play a role.

A vibration won't cause a tank slapper. If that were the case then all clips would come supplied with weights imo. As mentioned before, weightless clipons are pretty much usless for the street, but okay for the track where speeds are usually double or triple than that of speeds on the street. Slappers are usually caused by variations in road surface, ill tuned suspension, lack of or ill adjusted steering damper.

RESONANCE
CONCEPT
Though people seldom witness it directly, the entire world is in a state of motion, and where solid objects are concerned, this motion is manifested as vibration. When the vibrations produced by one object come into alignment with those of another, this is called resonance. The power of resonance can be as gentle as an adult pushing a child on a swing, or as ferocious as the force that toppled what was once the world's third-longest suspension bridge.


What this is saying is that if you were to have the correct factors vibration could become violent. There's a situation where a simple steady 15mph wind toppled the third largest suspension bridge of that time. So when the weights are taken out and the vibration is introduced resonance can occur. I don't know though maybe the chances are better that you will win the lottery so I may be wrong. My bad.

I understand what your saying, I just don't think the slight vibration in your clipons could get to the point where it can cause head shake. Afterall, the vibration is always there so to speak, the weights just make it so it doesn't translate to your hands.

On a side note, speaking of resonance, have you ever seen the footage of that bridge that collapsed due to this phenomena? Crazy.....

Yes that is a very crazy video. Wow what a little wind can do!
