Thursday, July 02, 2009 DMG head Roger Edmondson said on a call in radio show last weekend that he will be making an announcement this weekend at Laguna Seca about the 2010 DMG/AMA series. Edmondson said that he will be making an announcement regarding the Supersport class and that he will be making it from Gavin Trippe's display tent at Laguna Seca. Trippe is involved with the 450moto class (which is 450cc four-stroke, single cylinder engines in custom roadrace frames). Trippe has been trying to get the 450moto class stitched into the AMA roadrace weekend for several years. Edmondson making an announcement from Gavin tent at Laguna Seca certainly makes it sound as if Trippe's wish will be granted. Hmmm... Could there be a pair of Buell thumpers in the future (road and dirt)? This could be fun. G | ||

"custom roadrace frames" ???? what about Rolands SuperMono? No custom frames needed. MX frames, MX swing arms, MX mills.  (Message edited by barker on July 03, 2009) | ||

...what about to Rolands SuperMono?... Pretty bike. That looks like a great idea too. Technology already developed. Could be very competitive at a reasonable cost. Just the kind of class for developing young riders (and old farts having fun). G | ||

Barker said, "custom roadrace frames" ???? Rolands bike looks beautiful but I thought most AMA race venues were based strickly on stock configurations with "limited" changes. Isn't there a given number of bikes that has to be produced to qualify for entry in a given type of race? And if someone wanted to race his 450(insert brand here) super-moto bike in a race would it not have to run basically stock? Maybe its time for companys to produce a full fledged 450-650cc thumper sport bike. I'm sure they will be looking at the "market" for sales to see if it would be financially profitable. And Gregtonn, "Could there be a pair of Buell thumpers in the future (road and dirt)? This could be fun." Yes it would. Bob | ||

How about one based on a Royal Enfield:  http://thekneeslider.com/archives/2009/06/30/royal -enfield-bullet-sport-concept/ It's just a rendering so far. | ||

Hmmm... Could there be a pair of Buell thumpers in the future (road and dirt)? This could be fun.  Yep, now that I have committed funds and drained the accounts, Buell will go ahead and build it. The universe hates me. | ||

Is the KTM a one off or is it a race built bike by KTM? | ||

Is the KTM a one off or is it a race built bike by KTM? Neither. It's a kit. Check here. http://www.450gp.com/EN/index.html G | ||

Great idea, I think..I know of at least one old fart  that would love to have a street legal 450 class bike with the appropriate design details. The difficulty in the USA is that too many people think that if a bike isn't a billion CCs it's a toy..or a kid's bike or whatever. The rest of the world has a much better grip on reality... | ||

The problem with all these 450 bikes are that the motors are rated in hours before maintenance and rebuilds - that is not a practical machine for the street. EZ | ||
| Bikejunky |
If I had a 450 I would for sure do one of those kits. That is just to damn cool! | ||
| New12r |
The 450 spec class is not cheap, I know a guy with one and even with him machining all the custom parts still has over 9k in the bike. | ||
| Svh |
Even Rolands bike has a "custom" chassis. It is based off a mx'er but it is changed a bunch. I wouldn't mind watching them as a support class like the Redbull Rookies Cup. AHRMA I believe allows these to be raced and they look super fun. | ||
| Gregtonn |
According to the BeOn site, conversion from MX to GP and back is easily accomplished. This would indicate that chassis changes do not require frame modification. G | ||

A friend of mine built one using all kinds of parts. Nothing "one off" just bits from here and there. He has $4000 in the whole project. The problem with all these 450 bikes are that the motors are rated in hours before maintenance and rebuilds - that is not a practical machine for the street.  Honda has one too I think. | ||
| Froggy |
Hmm, perhaps I can take my Blast and change the connecting rod to decrease the stroke a hair to get it under 450... | ||
| Speedfreaks101 |
You can make the rod as short as you want to but it will not change the stroke, but you could offset grind the crank to get a small decrease. | ||
| Mr_grumpy |
Take a XB9r & lop the rear pot. | ||
| Kcfirebolt |
here's my friend Kevin's bike. He's built two of these and races them in Supermono and Supermono 2 with AHRMA. These bikes are damn fast and he'll get a full season or two out of a set of slick tires with no tire warmers.  | ||
| Kcfirebolt |
FYI, stock frame and forks. I think he has about $7k in it. | ||
| Ezblast |
FYI - those motors are still rated in hours - lol EZ | ||
| Glitch |
Really? What's the break down with regards to service? | ||

Kcfirebolt Posted on Saturday, July 04, 2009 These bikes are damn fast. Not that it matters but how fast is "damn fast"? I would be surprised if they are "as fast" as a current GP125... | ||

AMA PRO RACING ANNOUCES INTEREST IN 450 SINGLES CLASS 07/05/2009 AMA Pro Racing announced today its interest in a 450cc singles class for future AMA Pro Road Racing seasons. The purpose of the class would be to provide a gateway for young regional riders to ascend to the national ranks of professional motorcycle racing. Over the coming months, AMA Pro Racing officials will begin the process of testing the concept for performance, competition and safety characteristics as well as viability and interest in the marketplace. Preliminary plans call for the entry-level professional class to feature an arrive-and-ride format utilizing a single, yet-to-be-determined manufacturer and 450cc single-cylinder motorcycles prepared by a single tuner. Entries in the class would be restricted to riders between the ages of 16 and 21, supplanting the requirements for AMA Pro SuperSport presented by Shoei. With the inclusion of the new class, the age restriction on AMA Pro SuperSport would be lifted, allowing the class to continue as an option for young riders while permitting older entry-level riders an opportunity to enter the ranks of AMA Pro Road Racing. "Combining close competition with affordable equipment provides a win-win situation for fans and riders alike," said AMA Pro Racing President Roger Edmondson. "The parity in performance brought with a single manufacturer and tuner puts America's young talent at center stage and helps them to refine their riding skills for advancement through the ranks." The new class would borrow from Gavin Trippe's inspiration of repurposing the large, readily-available pool of 450cc four-stroke dirtbikes present in America for entry-level road racing competition. AMA Pro Racing is exploring the advancement of that vision and the potential to work with grassroots and national amateur motorcycle racing organizations to create a pipeline for young American talent that would culminate with an entry point to professional racing in AMA Pro. AMA Pro Racing is the premier professional motorcycle racing organization in North America, operating a full schedule of events and championships for a variety of motorcycle disciplines. From its Daytona Beach headquarters, the organization operates and manages AMA Pro Road Racing, which includes AMA Pro American Superbike, AMA Pro Daytona SportBike, AMA Pro SuperSport and AMA Pro SunTrust Moto-GT. AMA Pro Racing also manages and works closely with the day-to-day operational organizations of the AMA Pro Flat Track Championship and the AMA Pro Supermoto Championship Series in addition to other two-wheel and ATV series.

Well it looks like Buell may not be involved but, if Laguna is any indication, DMG knows how to set up a very entertaining MC road race series. G | ||

You folks might also be interested in this, the Moriwaki Honda MD250H...   "Honda Australia’s Moriwaki designed 250cc GP race bike - the "GP Mono" (MD250H) will be eligible to race in the GP125cc class this year, according to rule changes approved by Motorcycling Australia (MA). The MD250H is powered by a modified CRF250X engine. The four-stroke, single-cylinder motocross based powerplant is housed in a Moriwaki built high specification twin tube chassis derived from Honda's 125cc Grand Prix machines. USD forks, radial caliper, dry weight around 85kg. " http://www.mcnews.com.au/NewsArchives/2008/January/moriwaki_125_legal.htm http://www.hondampe.com.au/repository/motorcycles/press_releases/road-racing/MD250H.aspx The Moriwaki has been allowed to race here since 2008 in the GP125 class at club, state and national level. "Not that it matters but how fast is "damn fast"? I would be surprised if they are "as fast" as a current GP125..." It seems the GP125 class is slowly dying here, but the MD250H has set a fastest lap for the GP125/250 class at one track at a state round this year. So in theory a 450 in a good chassis should be quicker... | ||

PS I'd love a street version... 450 or 250... | ||

Well it looks like Buell may not be involved but, if Laguna is any indication, DMG knows how to set up a very entertaining MC road race series. G What part was interesting? the part where the riders nearly collided with the "safety car" or the press conference where Mat Mladin said no one will say anything about this until someone gets killed because of fear of fines and retribution???? This would be a great series if it were handled by someone other than DMG..... |
