grantrd: The nsr 500 made between 190-200 horsepower towards the end... No traction control and 2 stroke power delivery... Mick doohan was genius with that bike....
The previous generation 990's didn't make much less power than today and they didn't have traction control....


Just for comparative purposes, Doohan's NSR500 of 1998 delivered 180 bhp at 12000 rpm with a quoted top speed of 190 mph.

In the last year of 990, the Honda RC211V delivered 250 bhp at 16,500 rpm.

Realist: Pretty soon it'll be....."Marquez is winning because he has a thumb brake"


True Realist. Anybody want to bet that when MM clears off in 2016 all those 'year zero' yellers will cry foul play AGAIN?

Doohan had the best bike on the grid for his entire career, you all know that.

Marc happens to ride in a different era but Dani, Jorge and Rossi all have the benefit of more 'electronics' than Doohan.

Are you going to strip Jorge of his title? And Casey? And Vale post 2001?

And while MM has it better than Doohan, Doohan had it better than Kenny, who had it better than Mike.... and on we go.

Things change. But the best riders still win. Alas some of you can't cope with that, for whatever reason, so denounce the series.

I always preferred Rossi to Jorge and Casey, but when the latter two won, I accepted that the best man won that year. Why you can't do the same I don't know.

VonS: He will be better than Doohan.


only doohan didnt have the "i save you whatever mistake you make ecu" for me thats a way bigger achievement!


Yes but the NSR was only about 160 BHP about a 100 BHP down on todays bikes. I'm a a Doohan fan and always will be.

The NSR already made 165hp back in '92. The last generation NSR500 was at 180hp. It also weighed only 115-130kg, depending on the year and regulations, whereas the current bikes put 165kg on the scale.

Regardless, racing a two-stroke with that much power and that little weight is truly a scary endeavor that requires big balls and ultimate rider control & attention at all times. Even a momentary lapse will make it chew you up and spit you out in just a fraction of a second.

Don't forget those NSR's also knew what gear they were in and had different ignition maps for each, so "full power" wasn't available even though "full throttle" may have been.

Given that after only a handfull of laps you'd know what gear and which rpm you'd be pulling in every corner on the track, one would be tweaking the ignition maps to soften the power where necessary.

Just to clarify, Marquez's braking style is not aided by electronics. He tips the bike into a corner balancing the bike on the front wheel, with the rear wheel slightly off the ground. The natural tendency of the bike in that configuration is for the rear wheel to either try to climb over the top of the front wheel, due to the torsional force exerted by the turning front wheel on the resisting frame (with rear wheel and rider attached), and the wheel dragging the frame around, or the back wheel trying to pass the front - usually to the outside, due to the deceleration of the front wheel, and the tendency of the greater mass behind, finding a way past the hinge (at the steering head). With the rear wheel somewhat airborne, or completely unloaded, the front tyre is highly loaded, and the demand on its grip close to exceeded. Generally, adding the lateral force of tipping it into a corner is asking a bit much, unless the point of balance ofthe whole mechanism is so perfectly directed ove

Guna4699: we are already having a glance at what future holds.,, A Honda snooze fest again... until or unless Yamaha really steps up with something huge out of their sleeves...


This was predicted last year by people in the loop. When the new rules come out (less fuel in 14) Yamaha because of there basic design would be in big trouble .....actual quote was something like " an insurmountable hole"
All the MM fan boys can thank DORNA for there faux hero breaking records.....the next Doohan !! I just want to thank DORNA for screwing up what would have been the greatest season ever with the rematch of Jlo vs MM but **** no ....lets screw with the rules until one manufacture can no longer compete. Google and you will find this season was predicted spot on.

**** DORNA AND THIS FORM OF MOTOGP
