Don't forget ATK, credit Canondale, for F.I.
And Aprilia of course on the 450/550 V-twin.
so bmw and harley going head to head with new rotax powered dirtbikes, eh? this could get intersting...
honda also has FI, but its on the 250 motor used in the montessa trials bike. (cota 4rt?)
Yep Cota 4tr. runs fuel injection, but it doesn't have a battery. very trick.
Could this be the prototype of the new Buell 450 dirt bike?
Too bad they went with a link-less rear suspension. KTM has never been ever to dial in that setup. I hope BMW can.
If BMW comes to market with this bike the same time as HD/Buell the off road market is going to be awful crowded. Well competition is usually a good thing.
As far as the counter sprocket/frame issue the bike is a protoype, but its also a BMW they've certainly done things just as silly. Is it possible the motor is a 400cc its looks like the top end says 390 something?
looks to me like the countershaft would go clear out into the frame, and that wierd cap on the frame is probably some bearing carrier. to change the sproket you pop the cap/bearing/carrier doohickey, then the shaft would probably slide out, and the sprocket would drop out or back.
Are there any photos of the rear shock mounts ?
Looks like they have tried hard to keep all the weight very low.Looking at the seat there appears to be no tank and the forward lean angle on the motor.
Max, yes that the idea. Looks like BMW have not followed KTM's silly PDS with the offcenter shock mounts.
Wy in gods name did they amputate the other pot, now they have e long engine without the benefit of te second cylinder for more Oomph
But it looks nice and lean, so good way to go!
What's silly about the offcenter PDS setup of KTM?
You think Buell would run a prototype in a race of the german championship and just write BMW in the entry form? Quite stealthy.
Ok, a light weight enduro bi-cilynder is the BIKE most of us are looking for
...but.......... the bike is based on an aprilia,
Why shouldn´t we buy aprilia directly?:huh
What improvements BMW offers to potential buyer in its re-styled aprilia???:huh
Anyway, the question is.......
is this the bike that BMW official team could use in DAKAR?, i am asking this becuse current dakar regulations authorise bi-cylinder bikes below 450cc.
I´ll keep an eye on this bike, could be a good replacement for my KTM525
Wonder if the thread opener pics are from 6days.eu.
Nah. Just more Buell stealthiness.
so..............do you mean it could be a joke from them????????
Well believe it or not, but Gottfried Michels of Pami started tuning SR and XT's and then came the Priller Pegaso Engin with its 5 valve head, and he went modern, but that enging dropped out every other race so he took hold of the old Yam again... And then came the BMW modified engine, and it was rock solid, tunable to 75hp, and eventually he got the Job to build the engines for the Dakar "650's"
