not necessarily, a well setup bike, long swing arm etc will stay down fairly well, watch this zx10r

I would not want to go that fast on that surface :0, looks terrifying

I know that bikes have hit 195mph from a standing start down the two mile(ish) straight at Snetterton, but probably not long enough to get a barge doing anywhere near even with a run at it.

come again?

since when has the (back) straight at Snett been 2 miles long?

[Red16]

DanGPR said:

Yeah, am aware of that, takes away the ability to go around corners properly when its 12 feet long though,

I know what you mean. That said you wouldn't go and build a 300, 400, 500, 600bhp bike for trackdays and scratching would you? Horses for courses and all that.

ok havent seen it mentioned yet, and its hard to get in there first.... have you tried a chipped 335d ??

and while we're there surely you could it on a big conveyor belt doing 200mph in perfect safety and have zero risk of the car taking off...

got to love the internet

[Redbaron1973]

surely the easiest way to do 200mph is buy a used competition drag car... run it up the pod a few times then sell it on before the season begins.. overall the costs cant be too great?

[GingerWizard]

I always wonder if there are people utilising roads such as these in the USA....

Really? From what I can remember, none of the current litre bikes are geared for much more than 186mph, the Hayabusa was capable of it at it's top end, but even then I read an article in a bike mag about some guys trying to reach 200mph on it, and they only managed it on a slight downhill gradient, hugging as close to the bike as they could with a tailwind.

Stock original shape 'busa will struggle to do a true 186 in neutral conditions. The engines are very tough so can take a lot of tuning work. They will manage 200 with minor work (ie, full race exhaust, filter and careful setting up), a skinny rider and not unfavorable conditions. Stock gearing a 'busa will run out of revs at about 195mph, but doesn't have the power to exceed about 183mph.

You can get a 'busa for £3k easily and the work required would cost a lot less than £2k. If you were lucky the £3k bike would have a decent exhaust system already removing the biggest extra cost.

Following is a graph of thrust at the back wheel through the gears against speed on a stock 'busa on stock gearing. The black dotted line is aerodynamic drag (based on a cda of 3.36):-

ZX12R might be easier. They are cheaper to buy generally and have more power although worse aerodynamics. I have done over 200mph on a borrowed one of these at Elvington (pipe and filter and carefully set up), but I am only 5'8" and not that big (owner is bigger and on the same gearing could only get 193mph). Same bike is now bored out and I have done ~197mph on it in a standing mile.

Easy enough to do on a bike, £5k would see you through 200mph easily

Really?

Probably not as easy to do on the autobahn as you might think.

A standard Honda Fireblade hit over 200mph this week when, in the hands of female racer Leslie Porterfield, it broke the world speed for litre production bikes at Bonneville Salt Flats.

[underdosed]

I have had a run at bruntingthorpe in a gallardo and only hit 160mph, as said before you need serious power to get to 200mph.

[skyline sam 82]

Ive been i my friends lamborghini murcielago with 590BHP 6.0 v12 and although it boasts 200mph+ in the real world it will only just get past 189 mph so you will have to find something with some serious power. or a nice bike

Bruntingthorpe, Elvington, Woodbridge, Santapod have seen cars well over 200mph

but there not 'driving experiences' where you pay a few hundred quid for a passenger ride

A dragstrip is too short for 200mph in anything other than dedicated drag racing machines. Even F1 cars would struggle to hit 150mph on a dragstrip.

Pendine Sands not been mentioned yet if you don't mind getting the car dirty.

On a bike it can be managed without too much of a problem (there are a couple of ~2 mile long runways around). Cars struggle more although I think a somewhat tuned Viper managed it at Woodbridge a couple of years ago.

Most cost effective way to do this reliably has got to be an M5 or M6 and according to auto trader that's 15k + a visit to DMS.

"DMS provide an upgrade to the management system that takes power to 548 BHP, torque to 411 lb/ft (556 Nm) and 200 mph top speed capabilities. The upgraded software was completed after hundreds of hours of design and testing on its own development M5."

Had this upgrade on my E60 M5 & although i never managed to hit the magical 200mph, i was well into the 180's (speed trap) at VMAX & had all of 7th left so am confident it would hit a genuine 200 with a long enough stretch of tarmac.

Managed a genuine 197mph in my GT-R (630bhp) & had anough revs in 6th gear left to hit 200.

check out my post on page 3 of this thread, my Viper mate drove all the way from Ireland, did 215mph@Woodbridge then drove back home to Ireland

Mr Gear must mean 1/4 mile dragstrip, avon park, santapod

I do indeed mean 1/4 mile dragstrip, and I stand by what I said. You need something immensely special to hit 200mph in 1/4 of a mile. Bear in mind that you'd only have about 6 and a bit seconds to get there and you start to realise how difficult it would be!
