BMW HP2 in LW??

[xseal]

I think CCS needs to consider whether this is a LW bike, or just a thunderbike, or something else.

The HP2 Sport keep the 1170cc (101.0 x 73.0mm bore x stroke), air-and-oil-cooled, opposed Twin ("Boxer") engine of the R 1200 S, but the engine has been fitted with chain-driven, double overhead cams in place of the High Cam and push rod configuration of the R 1200 S

Peak horsepower output is claimed to be 128 at 8750 rpm, while peak torque is 84.8 lbs.-ft. at 6000 rpm (up from 122 bhp @ 8250 rpm and 83.0 lbs.-ft. of torque @ 6800 rpm on the R 1200 S).Peak horsepower output is claimed to be 128 at 8750 rpm, while peak torque is 84.8 lbs.-ft. at 6000 rpm (up from 122 bhp @ 8250 rpm and 83.0 lbs.-ft. of torque @ 6800 rpm on the R 1200 S).

Sounds like the next hot-setup!  I love to see new LW bikes being designed that push the current boundary of Light Weight.  The FT500 was killed by the Hawk, the Hawk by the SV, the SV by the Buell, now the Buell by the BMW.  Change is good!

I'd call it a middleweight, especially if it's true that Nate may race one in AMA FX.

I am told if it fits in the LW Class rules structure then it is lightweight. If it's good for one it is good for all regardless of the HP value.

If you think it does not fit the spirit of the LW classes, you can write to Kevin Elliott and give him specifics on the technical reasons it should be disallowed and it will be considered for next years rules.

Do it now, as it's the end of the season and they will be reviewing rules very soon.

CCS rules allow twins up to 1100cc's with four valves per cylinder in LWSS.

This is an 1170 with four valves per cylinder.  It gets bumped out of LWSS, but still allowed in LWSB according to a quick look at the current rules.

Yikes.  The air-cooled stuff is starting to get out of hand.  When you've got bikes that fit the rules for LW putting out stock HP and Torque that would make MW guys jealous, that's a problem IMO.

Ridgeway,
Remeber what you said on the other thread?
Quote "--------------------------------------------------------------------------------
An F2 being comparable in performance to a LW bike does not make it a LW bike.  Period.

Using that logic, the Roberts clan should be able to run their GP bike in WSBK.  As far as the actual rule modification goes, do you really expect the rules for LWSB to be modified with a "P.S. Honda F2's are allowed"?"

If it fits into the rule structure then run it. We shouldn't change the rule to exclude the newest bike if we don't change the rule to include the oldest bike. Lets leave it as it is and when a bike isn't competitive anymore then that guy will have to deal with it.

My thought though is this. This is "club level racing". This is more of a sportsman type of organization. If you wanna make something of it, go with ASRA.

exactly, this is club racing, that is why a $30,000 motorcycle shouldn't be lgal in lightweight.

This says it all how can middle class people out for a fun weekend trying not to spend money compete with some one with so much disposable money.
If you can afford a bike like this to crash, go race with your other showoff friends

Rules are rules, folks.

I'm sure Ed Key might not want to think about how much time and money he's invested in his supersport bike.  TZ250's are very expensive also.

If someone can figure out verbage for rules that make it that you can only spend so much money on a bike, please feel free to submit it to CCS.

Racing is about solutions, though.  Decide on your best bike, develop it with the money you have.  Figure out low cost solutions.  A lot of those are about developing one's riding, a cheaper solution often.

A lot of that stuff has been available on the books for years and years and years and years.  But seldom does that stuff come out.

There are air cooled two strokes that make 120 reliable HP that could be ran in Lightweight.  But there aren't many of them.  Similarly, I don't expect a whole bunch of BMW's to show up.  Nate's been on them for a good while now, and I am still waiting for someone to do one up for the midwest.
