I've seen it mentioned: "I have often wondered how the spitfire was able to achieve 120mph out of the box (if it actually ever did)"
I've also read period "tests", which quoted 125mph, without verification.
So, are there any verified results of just how fast a stock Spitfire can go?
Inquiring minds want to know.

Megacycle track cam (x12) 32mm concentrics, small port head with big valves, and my own style 2-1 (short pipe) with long dunstall silencer. Could probably get more by adjusting the cam timing and tweeking jetting further. But im pretty happy with what I have their as a road bike.

also sheading some weight from my ever growing fat ass will help laughing

When I first put my Lightning back on the road I remember opening it up once and seeing around 110 on the speedo. It was so hard to ride like that that it didn't last long. The wind speed was trying to pull me of the handlebars and I can distinctly remember hardly being able to keep my feet on the footrests because everything was vibrating so much. The madness was cut short when my right foot vibrated onto the gear lever and managed to slip the bike into a false neutral. For a split second I thought the engine was going to explode and come through my arse. I calmed it down a lot after that.

I've probably run my Thunderbolt up to 80 or so, it wasn't particularly enjoyable! Fastest I have been on 2 wheels was 95 mph on a brand new 1980 Harley Davidson Sturgis. High speeds have no allure for me on 2 wheels.

very easy to start-- almost no compression to fight!

Is there a sidecar on it?

Awesome video.

Not to be outdone by other posters, my skateboard will do 45 MPH downhill and 50 MPH when I have a beer in my hand.

The photo-reconnaissance spitfires were the fastest overall, well over 400mph in most cases.
