BOS exhaust: Why not three?

Interesting exhaust, not my preference though:

Yuk!...when Kawasaki first released theirs (with two pipes like that) I thought that's the first thing I'd change if I bought one.

I wanna be able to see the wheel.

I like the novelty of it......
but a Beemer 'Busa killer shouldn't appear "novel." Still, I like 'em.

when BMW starts to copy Ducati.... oh wait, the double muffler, the under-seat exhaust - all earlymid '90s Ducati design executions. Still, copying something beautiful never hurts.

You ain't seeing the wheel if you're riding. I think it's unique, not dissimilar to the character of the bike itself. Didn't see it listed on the Bos-exhaust web site thought. Wonder how much.......

after going away for a few hours & coming back - I like the two smallish cans MUCH better than the giant eye-catching can from stock. Probably does not save any weight over stock, but I'll bet it sounds good, no?

You gotta stop at the gas station. and may have to look at that thing.

I would go with the can from the PowerCup bikes. I think that it is a Remus and it is smaller/lighter.

The exhaust for the power cup bikes are exclusive to the bikes running the series. They run stubby versions of the Laser HotCam not available to you and I schmucks on the street. I don't think I'd want to either. I wouldn't want to announce my every move and constantly listen to the howl they produce. Great for the track, not for the street.

I've ordered a new exhaust (not the BOS) and other goodies. Had a heck of a time trying to find one w/o the mfgrs emblem pop riveted on. I'm still not convinced and confident that it'll arrive that way.

Well, don't keep us in suspence; which pipe did you order??

While at the International Motorcycle Speed Week at Bonneville last week, San Jose BMW had their Power Cup bike there, we removed the Laser pipe and installed the Remus Titanium set, head pipes and can. Lighter in weight, better sound and worked just as well if not better.

By the way, I spent some time riding the Power Cup bike, (oh darn), talk about responsive power and handling, be still my heart, 140 plus MPH with out even trying.

Nice DeanO....is that salt caked onto the radiator??..how'd that effect things???

What's the silver bike behind it???

What's the traction like on that stuff....any speed wobbles??

No speed wobbles, you do not turn very sharp at all but a hoot doing 140-150 MPH power slides. The Power Cup bike is fantastic, extremely controllable, full throttle in 4th sets up fantastic wheel spin totally comtrollable with the throttle. The Power Cup bike has a backward shift pattern, ie up for first and with a power shifter, no clutch full throttle and just hit the shift lever. if you do it just right, the rear wheel just keeps spinning even at well over 100. The most fun $29,000.00 motorcycle that I have ever ridden. It is truly a step above the standard K1200R which in itself is fantastic. Yes the salt packs everything but no heating problems were encountered. I can not get the impression of riding the Power Cup bike out of my mind.

The silver bike is Chrises 1978 R100RS bike that he went 162 on the salt with and won the Airhead invitational Road Race in Georgia year before, last, this last year he won the Air Head invitational with one of his old 750's from the '70's, both years Brian Catterson of Cycle world Mag was the pilot.

I ran my ST and hit 144.4 at the rev limiter. Way too much fun.

Dean is truly filling his cup (of life) while he can. There's a role model for you.

rivi77.....without going into a technical disertation....large internal volume exhausts enhance the torque band in the low and mid-ranges, low volume enhance the top end.......racing bikes spend most of the time in the upper quartile or the rev band.....hence the short stuby exhausts.

BTW, are you planning on a laser Exhaust and another trip to the dyno?

Inquiring minds want to know........
