Most beautiful 500GP bike ever?

Is that the 500 or the 750,hard to tell.BTW Bluegreen,the Yamaha World Champs 77-80 dvd may fill in a few cracks in your collection.I did a quick review on here.



That was my first reaction too ..... the 750 looked wider as does that bike.
 
and the other an older Repsol bike, maybe 94.

Pretty cool trophies



It wasn't Repsol in 94...





Ur not a fan of unique bikes then. Date Rocket Rons bike, they were cutting edge bro.



Cutting edge perhaps, but they cut the wrong edge. Maybe someday that solution will be advantageous, but then and even now it isn't happening



I`ll ask again,does anyone kbnow what happened to the Vyrus moto2 machine.Similar set up.



My understanding is that it's for sale at a few different spec levels from Vyrus, but they are struggling to generate the interest required to get some testing done with a top end race rider. Without that they cannot get feedback on the projects potential in competition
 
Absolutely,the thread wouldn`t be complete without those.Now.....where`s the v8 `Guzzi !



That was really ugly though...

Chops, Rons bike wad badass compa. $10 says peeps are Googling the .... out of that 'fork'.

How dare you sir! I'll have you know that i love all motos even crapping edge bikes like the ones discussed...

and Rons bike sucked ... i have it on VHS compa

I think your wrong there Tom. The Elf bike used a twin wishbone chassis with hub centre steering. The proplem that was inherrent with hub centre steering was bump steer, this is where the wheel starts to steer as it moves upwards. Cars of this erea also suffered this but it was less noticable in a car. Using todays technology i doubt bump steer would be a problem.

Road bikes have been produced with hub centre steering and from a sales point of view were a flop. It seems bikers dont like change and we would rather stick to conventional fork systems, even though they have inherrent probles like rake and trail reduction under braking.

Well although some of the issues experienced the first time around might be solvable now, until a solution like this is proved successful then it cannot be concluded that it is superior. Although i have mentioned earlier in this topic about how conservative riders tend to be and the problem of control tyres

Well sadly thats not likely to happen because there is no real interest in any ststem other than conventional. Why? because it just doesn't sell and that was proved. Thats why calling motogp a prototype series is a ....... joke !
 
Spot on compa! Tell that to the sudden crop of "purists" who think the end of "prototype" racing is happening in 2012. Haha

Quite right sunshine, who the .... thought of getting rid of rotary engines was a good idea ?

It is still a prototype series if all the entries chose to implement very similar solutions, although not an especially innovative one. The prototype thing only starts getting damaged when the rules start dictating the solution, control tyres is clearly the worst example of this.
 
I'm dont know much about them, but surely a high revving, less moving parts, more compact engine is a good idea in a motorbike?
 
Surely material technology has moved on, I know that rotor tips need to be hard as ...., but if Mazda can make a Le Mans winning car back in the 90's with a wankel, they could do even better now surely?

The definition of prototype.

"the original or model on which something is based or formed".

Dont you think the 4 stroke engines in chassis using conventional suspension ect that we have in motogp are streching this definition a tad ?

Another problem with wankel engines in bike is the total lack of engine breaking. Having said that im sure this can be over come with development.

I thought motogp was about prototype development but if you look at it realisticly, its just tuning on non original technology.

No not really, if you are going the definition route then anything is a prototype on the basis that it's a work in progress and/or not a finalised design rather than a production item

I'm not majorly up on the whole Wankel thing to be honest, there will be people on here who know more, or you could probably find something pretty good on the web. I know their power delivery and inertial characteristics will not be the same as a conventional motor
