RB Racing rant...man I hate to fuss...

A few conditions in buying an RB Racing 124 Challenge was (and actually number 1 was the main reason):

1. I would buy their product IF it wouldn't drag the asphalt! I asked if their exhaust build prevents the pipe from dragging the asphalt on right-hand sweepers...they (she), of course, replied with an emphatic "Yes, will not drag."

2. Performance (engine) will not be reduced following their exhaust install on my 117...which was obvious.

Well, to those who want a pipe mostly due to number 1 above, you may want to consider another option as the RB Racing 2:1 124 Pro Stock Challenge does drag the asphalt.

I'm not roasting RB, by no means...I am, however, letting those know who may be flirting with a 124 Challenge to keep this in back of their mind before purchasing, despite what they (she) may allege.

And no, I didn't lay the bike over. I was 1-up, I weigh maybe 195lbs, stock suspension, not doing anything other than riding it like any other time.

Ok, I'm done...thank you ...:angry:

Midwest, could you get a buddy to hold the bike at an angle where the pipe is touching and take a few pics? I'd be interested to see how much lean you get. I'm considering a set myself...

Thors, will do on Tuesday evening. We have a ride then and we'll put the phone cameras to work for you. Probably won't be able to report back to you unitl Tuesday night/Wednesday morning...but again, will do.

Aspen, ya know I wasn't THINKING it was anything out of the ordinary as far as a ride goes...perhaps the photo-op will tell the entire story for us though... Hopefully it won't go like this "So we were trying to get a picture of the lean angle the exhaust provides, and look what happened."

I use to seeing the pipes drag at the back, I hope the pics come out well, I do want to see them

Aspen, looking at your bike I see the V&H BR's...I had those on my K9 originally and they would drag the asphalt horribly bad...even had them cut and they would still drag. AS A MATTER OF FACT, the day I rode my K9 from picking it up new, pulling out of the dealers lot - the V&H BR's hit the ground. We went back and forth with V&H over a few months, turns out the set I had was their first version on BR exhaust for the K9 and was trouble....trouble in the sense that the pipe hit the ground hard. A buddy of mine has a newer version which appears to have a different angle or sweep, he's never hit the ground with his.

Awesome pics, thanks!! By the looks of the second one your peg would hit well before the pipes. How the heck did you drag the pipes?

Thors, yea the pegs are all chewed up and have been for awhile. And I have no idea what the hell happened on the pipe hitting the asphalt. Seeing the pictures makes me question it even further...

Easy explanation. Simply leaning a bike over doesn't fully simulate riding ground clearance. With you sitting on the bike you are loading the suspension. Also, depending on whether or not you have a road which is rising to meet you or falling away from you also determines suspension loading which also affects lean angle ground clearance. Pipe is still giving you more ground clearance than most. I'm trying to find the perfect one myself.

Wonder what the recommended lean angle is. I'll bet it's less than what he's showing in the picture which looks close to 45 degrees. I know it's hard to tell from the picture. I have seen people riding ahead of me that appeared to lean way farther than necessary to navigate said conditions with given speed. Just my opinion and observations. need a road racer to chime in perhaps:)

As someone who has done plenty of track days, the explanation I gave is based on my experience at the track and common tech. today. There is no such thing as a "recommended lean angle" for custom motorcycles. Typically most builders don't give much thought to handling in the curves. Just needs to be safe. Big Dogs actually handle well for what they are and the engineering behind their handling is sound. We just need more ground clearance.

And therefor the need for 30"wheels:)

When I restored my bike I called them about a two into one exhaust. I talked to Richard Crainium. Him and Mr. Attitude pissed me off and I said screw them. Another member on here spoke to them afterward and had the same experience. There are a lot of companies selling exhaust pipes and most are more realistic on the price.
