Motu this one's for you https://www.facebook.com/video/video...52818502565534
Great to see another old American Motorsickle company revived. Motu will want one ( in about 10 years)
Do they have gears!!
So they got Joe Kopp off that Ducati - it was faster than the Harleys so they had to fit a restrictor to it. They'd have to make the Triumph frame out of tinfoil to get it light enough surely ? Great to other brands in there now to break the XR750 monopoly....mind you, you can't buy an XR750 off the floor anymore - but some castings and machine them yourself to get an engine.
If you've never seen a Mile, take 50 minutes and indulge yourself in some American hype. There is a Triumph in there somewhere, but it's more about the Kawasaki and XR750. A couple of chicks too. The speeds are deceptive - 160kph in the turns with an 18'' groove....400mm say.
Is that Chris Carr talking about hanging his handle bar over the fence to stop anyone passing him by drafting ? . Thats guts or a total lack of brains, I'm picking guts. Watched it early this morning. Worth a look if you ever wondered what flat track is about. I don't quite get the engine rules any more. XR 750 are considered to be a race motor & are limited to 750cc & run restrictors , but the likes of the Bonnie & Duc are street based motors so can be bigger, up to 1250. Is the Kawi still a 650 without restrictors or a restricted 750. All seems kind of ad hoc to me.
Yeah, I'm not too sure about the rules - they want other makes of engine in there, but don't want them running all over the XR750. I can sort of see that - it's won more races than any engine on the planet, it'd be a shame to see it go. When Joe Kopp won on the Ducati a couple or so years ago they slammed restrictors on it straight away....but then the XR750 is already restricted. Bill Werner who built the XR750's for Scott Parker was the first guy to get the Kawasaki working, from what little I've been able to find out he used several different cranks and also different capacities, depending on the tracks. Looks like nothing can still hook up like the Harley though. I hear someone has assembled enough parts to run a Honda RS750 this season.
They can't twingle the cranks on the bikes , is that why the Kawi has a power advantage but does not hook up as well as the XR. It might be one factor in favour of the Bonnie with 270 crank . It's the most primal form of racing, even more so than speedway imho.
Well doesn't the Bonnie have a 360? The Scrambler and America have the 270. Dunno what they are allowed to do these days, but Werner was talking about different engine configurations and capacities, but he's not going to be giving away secretes on the internet. The English had a hands off approach to speedway and let the bikes develop themselves, only locking in the rules when it was the bike we know now. The Americans tried to stop the factories taking over, so made the rules bikes you could only buy of the dealers floor, so that's why they resemble a road bike. Rumour has it that the last pre unit Triumph duplex frame was made for flattrack, it certainly had a steeper steering head angle...and was pretty nervous to ride. There was the 200 unit homogulation rule, then they allowed frames like the Trackmaster and Champion. In the '80's they only had to use the engine cases of a production bike, which is where the NS750 came in, a CX engine turned 180. The RS750 used the XLV750 engine cases, and the XLV750 was never even sold in the US. just read that rule book - the XR750 and RS750 are the only race engines. Twingle was a term Werner used when he made Scott Parkers XR750 fire both cyls as they came over TDC, there was no change to the crank, just cam and ignition timing, something you could do in the pits without even removing the heads. He did it for better traction on a wet track...he actually said Parker thought it was gutless and rode it harder. You could twingle a 360 crank very easily, only the cams need changing, not the crank, just like doing a reverse head Triumph - so I think they are talking about 270 cranks....giving the staggered V twin firing order which gives better traction.
I figured they would be using the scrambler or cruiser 270 motor. They talk of using the speedmaster motor. I misunderstood twingling, what would that set up is like vibration wise on a 360 twin
I think the AMA has misunderstood twingle, it would offer no advantage. But a 270 crank would. Triumph has both 360 and 270 cranks...is that a sneaky advantage ? New rule coming !
The Picture on Marlon Brando that inspired Motu to get a Triumph.... Cool speed effect on the spokes too.
Harleys new works bike
Springfield Mile http://www.youtube.com/watch?v=rRePUj3WL98 Explain to me Motu, why did Brian Smith take a dive to the inside when he had enough horsepower to hold off everyone on the outside line. Seems like he managed too snatch third from a sure fire win. Tune in at about 39 mins if you cant be arsed watching the whole thing.
Thay better watch out when i get my G5 going, By crikey
