The bike is an SP1 and is capable of about 165mph. The copper was in a plane above and 'timed' him on a manual stopwatch between two marks on the road. Independant dyno testing of the bike proved it was impossible for that bike to do 205 and it was far more likely that the copper was 'trigger happy' with his stopwatch.
There are bikes that will touch that sort of speed. Suzuki Hayabusa would just about do it when it was first launced as will a deristriced ZX12R . However all the jap manufacturers now have a gentlemans agreement to restrict bikes to 186mph(300kph)
So yes it is possible for bikes to do that sort of speed but they are few and far between.

I had a Yamaha RS 125 in late 80's and did a lot of tuning up of the little engine, (125 was the limit on a provisional when I was a lad Kipax 
) By tuning up I mean buy all the bit's and go silly with a file for a day or two.
The way we used to test the top speed was to go on the East Lancs rd ( dual carriageway ) and assume the best wind resistent riding position.(head on the tank looking right, left hand on the left fork, right hand on the throttle, Mate on big fast bike on your right to ensure you hit nothing,and confirm your speed, as this position means you see very little but get crucial extra 5mph.)
As I got to my top speed my mate dropped back, I wondered what the h*** he was doing,and for one stupid moment wondered if I had outrun him, when a capri 2.8 police car pulled up along side
I sat up and slowed down but ...
I have a speeding ticket for 103 mph to prove my little shed could beat the TON The only speeding ticket I did not mind recieving..

Yeagh i remember yamahas .. at the time they had the fastest 250 on the rd...
A suzuki, honda and I think yamaha 250 and the next bike up..380 for suzuki... all looked the same and the gt250 was a badge on the oil cover.... people where buying 380 and simply replacing the oil cover to fool the police into thinking its a legal 250 with l plates
but when your doing 80 down the dual cariageway and a yam 250 comes alongside... drops a gear and shoots off its a bit of a giveaway

The bike at the side of me while I was being silly was a Yamaha Rd 400 air cooled with 250 side panel's good fun.
My mate still has a suzuki 380GT Ram air, In his shed. Really nice sounding bike and went like Stink There was a suzuki 500GT ram air, Which was a triple cylinder sounded fantastic and was one real handfull, It either wanted to go slow or try and wheelie all the way up to 130. Real bike

But the true kettle was the GT750.
750cc 2 stroke water cooled. They were renown for the middle cyclinder going pop due to it not being cooled very well.
In reality these bikes had reasonable power but the handling/brakes/tyres were straight out the ark. The real improvements in modern bikes has come in these areas meaning corner speed can be held and modern brakes are truely awesome.
Also bikes were made as a 'cheap' method of transport. Now they are an expensive toy. People would just not have put up with tyre life measured in weeks 20 years ago.
