Yes, that is correct, its just a jap bike twin made in England pretending to be a 60's cafe racer.
Incidently Triumph was started by a German, went bust and was bought up by BSA....so they are not really British or Triumphs....

....Kraut BSA's

Your welcome to take it for a spin Mr Motu.....

I bet my bike could do 190kph too...

Got any R80 motors lying around?...

No,that wouldn't do. How about,ah...

you could bung in an R100 and call it a Nurbergringer......or TT replica....or Daytona.....BMW moved bike production from Munich to Berlin and put plastic guards on them.....not really BMW anymore as the B now stands for Berlin not Bayern...

To be fair - 'Thruxton' is one name modern Triumph has got kinda right in that it was the uber performance version of the bonnie. (the fact that the new bonnie is not uber anything other than ugly matters not)

I did a fair bit of reading about Thruxton triumphs once and one thing was clear - they did exist... Everything else was myth and exaggeration designed to sell some weeping wreck with funny handlebars.

It was an official model and (in theory) be ordered through any dealer. In practise of course it would only appear at your dealer if your last name was Hailwood or Duke or somesuch. Apparently one year they made 100+ and other years less than 5 and fuck all genuine bikes survive.

In NZ they were mythical - if someone had a very fast Triumph (ie 15% louder than anyone elses) it would be rumoured to have 'Thruxton cams' or pistons or whatever despite the fact that we didnt even really know what a Thruxton was - but it sounded cool...

In short - Mr Ed wouldnt let triumph go road racing BUT he would provide limited support for production racing (hence it was an official model). Thruxton was a production endurance race on an old airfield that was so dire today it would be considered too rough for motocross so the bikes were tough and fast.

Everyone was almost unique and all were handbuilt and rebuilt and modified to heck - I doubt any two were the same...

Yep

Ol' Softie, we call him now. He brought me beers so I let it slide that the atrocity was parked in my drive...

The other thing about the new Twuckston and the new Boringville is the Twuckston has 3 way adjustable forks- as in 3 settings of not firm enough.

If I was in the market for a road bike I'd get myself a modern Thruxton. I know they're rather piss weak power-wise, but like the bikes of old they're a perfect piece of kit for modifying.

I'll have to be careful I don't go down that track too much at the expense of the old bikes in the shed.....tempting though.
Shocks, emulators/springs, ditch the airbox and that might be about it.....

My impression was that the Meriden Thruxton was a specification, mot a model. Ie there was not a different model code issued for it (T120T ?) , but a dealer could, maybe, if he had the right connections getba Bonnie from the factory kitted out to Thruxton spec. WHich mainly meant a blueprinted engine and some cycle parts. Like the ISDT models.

I was dubious about the 230kph too, until I saw it had a "chequer stripe" everyone knows that ordinary stickers add 20kph to top speed and a checker sticker must be good for n extra 40kph. And the pistons are "increased by 90mm". Either the standard model has very very tiny bores or the Thruxton is massively over square

And I'm sure the Meriden Thruxton could do 140mph, cos my Thunderbird could do 125mph. Honest, saw it myself on the speedo, or good as , anyway. So with the advantages of an extra 200cc , DOHC and fuel injection (even if it does pretend to be carbs) , AND a chequer stripe AND those massive pistons the Hinckley should easily be good for 230kph. Probably a lot more, shouldn't be surprised if some people were able to report 300kph.

Given the value of the dollar at the moment a 988 big bore/stroker kit looks like excellent value ....

This kit requires boring of the cylinders and pressing in the sleeves as well as additional engine work. Check with Wiseco for specifics.

as in offset grinding the crank.....resizing the rods....rebalancing.......bigger carbs......
Apparently the head really benefits from gas flowing and the stock carbs are probably too small....
Tempting to just throw a set of 40mm Dellortos on and bin the CV junk. My BMW had CV carbs.....horrible things.

I think the whole bike is a decent sum of it's parts and mess with one thing and you may as well go the whole way.
Hot up the motor and the single disc will seem weak.. twin discs and now the forks seem weak, high speeds and maybe a steering damper and suddenly the money just flies out of your wallet

I tend to agree, I've only got 55 HP of riding ability.....If I wanted to go fast I'd have kept the Ducati.....

Next time I'm in the hunt for a new bike (or more likely low km preloved one) it may well be a late model Bonnie.

Quickly followed by boxes of parts and empty boxes to strip off stock parts and store them

Fatbars, suspension mods, exhaust etc etc

Ah what a project. A rowdy one too as all bonnies should be.

Interesting, as I prefer my Bonnie for it's more upright position lol. Tried some lower bars on her, but were a bit much on my elbows so stuck the stock ones back on.
