There are people who will tell you that the 1970 Trophy was one of the landmark Triumph motorcycles; one of the most well developed and stylish classics, and one of the very best to own and ride today. There are other people who will tell you that the single-carb TR6 of the very late 1960s was and is a better bike to ride than the Bonneville of the same era (in the following breath they’ll go on about the low-revving flexibility and clean carburation of the TR6, and the T120’s harsher nature, by which time you’ll be wondering whether now is an appropriate time to leave the planet). And there are even people who will tell you that the American specification TR6C, with its slim tank and high pipes is the most handsome, the most desirable, and the most luscious of the lot.

So we forgive Jerry Fiford for buying this one. Even though he didn’t mean to. Who wouldn’t have been seduced by such a sought-after machine? Well, his wife probably could have done without it – she was hoping for a new bathroom suite! Instead, Jerry came home one day with the Trophy… like you do.

‘I only went to have a look at it while visiting a friend in Portsmouth,’ explains Jerry; ‘but when I saw it I fell in love, and it just happened to be for sale. It’s a bugger when you know you can’t afford it!’

Slinky. The scrambler style of motorcycle was something of an aberration for Jerry, too, because his other classic motorcycles have usually been of the café racer breed. But there’s no clip-ons or rearsets on this Triumph twin – it would feel more at home competing in an American desert race than thrashing down the bypass to the Dutch House. Did Jerry know what he was getting into?

‘I’d never owned a big Meriden Triumph,’ he confirms; ‘only a Daytona 500 and a Twenty One. I was always into BSAs and Velocettes. I do ride a Triton with a Bonneville engine, though, so I half-knew what to expect.’

Or at least, Jerry thought he knew what to expect. But his 650 Triumph had a sneaky surprise waiting for him. The Trophy was being sold as totally renovated and it appeared to be ready to ride, so he collected it from Portsmouth and started to head for home. ‘Unfortunately,’ he reveals; ‘it wasn’t fully run in and on the journey back home it decided to semi-seize. At first I thought I had just run out of petrol — although it did stop rather quickly. After turning on the reserve it started again straight away, so I still wasn’t aware that I had a problem.

‘Then I took it on a South London Triumph Owners’ MCC club run. The people following me on the run reckoned that it was smoking slightly, so I decided to have a look inside. Yes, it had seized — but there was only a small mark to show for it on the barrels.

‘My next step was to take it to the local re-bore shop. They informed me that it wasn’t worth a re-bore and said I could recover the barrels with just honing them out. This they did while I waited – and £10 later I was on my way home. I ordered new rings from Len Baker in Norwich and they arrived in three days.

‘So I went to gap the rings, placed then in the barrels – and they fell straight through. Oops!

All is at it should be now.‘Next I measured the barrels… only to find they were at 76mm. That made it obvious.’ On a standard TR6 the barrels should have been 71mm, but on a T140 they are – you guessed it – 76mm.

‘I realised I had unknowingly bought a 650 Trophy which had been converted to 750cc. I don’t think I would have bought it had I known it had been converted to a 750, as I like my bikes to be pretty much as they were in the period when they were built.

‘I got straight back onto Len Baker who managed to find me a brand new, genuine Meriden set of standard 650 barrels and pistons. I got the engine rebuilt over the weekend. But next I discovered that the previous owner had fitted a 32mm carb to go with the 750 conversion. So had to buy a new 30mm carb to get the bike back to its correct specification.

‘That was it. I now own a correct TR6C and it is still being run-in (carefully!).’

Jerry’s Trophy is red, when he believes it would have been green originally. He has fitted a centrestand (‘because life without one can be a pain in the arse!’) and would consider making another couple of changes away from its original spec, like adding a rev-counter. He’d also like to address its taste for silent running.

‘I find that the silencers work too well,’ he reveals; ‘and it is a very quiet bike. I might try some different ones that make a bit more noise. With both silencers on the one side, only my left ear benefits from a bit of Triumph roar!’

So life so far with the Trophy has been… eventful. What attracted Jerry to the bike in the first place were its looks, the American styling which ‘makes it stand out a bit from the standard UK bike.’ Unusually for an US-spec machine, however, this TR6C never left the UK so Jerry has been able to trace much of its history – there’s no gap where it disappeared into the American mid-west for two decades!

Justifiably proud owner JerryMind you, Jerry is at heart a sportbike rider. How has he found riding the Trophy? It’s very different from his normal café-racer Britbikes. Has it lived up to its looks? Or is it all Show and no Go?

‘I can honestly say that for fast road-riding the handling on the Trophy is almost as good as on my Triton, although on a race track the Norton frame would be superior. The brakes on the Trophy are superb, being a twin leading shoe (I use the same brake on my Triton). I also ride a FireBlade. Sometimes jumping from modern to classic can be a bit scary — especially when you get to the first late braking point. I forget that I’m riding an old bike, but I can make the Trophy’s tyres squeal even when braking at a reasonable speed. The brakes are that good!

‘As this model was made for the Americans to ride off-road as well as on tarmac, I thought the gearing would be low, but it isn’t.’ Aha. You could eat your dinner off that. Assumming it wasn't soup or something runny, of course.Perhaps we can attribute this performance to the combined effect of the larger Bonnie valves and exhaust camshaft? These were fitted to the Trophy from 1967, together with a slightly wider single carb. The idea was to give the Trophy smooth low speed and snorting acceleration; the best of both worlds. By 1970 the TR6C was hurling out its 40-odd horsepower at easily accessible engine speeds. Steve Wilson once described it as; ‘bringing the revs flooding in at a tweak of the grip’ and maybe that’s what Jerry has been revelling in. Or could it be the delightful freeing-up of the motor, as the new metal surfaces get bedded-in?

‘The engine is still running-in,’ confirms Jerry; ‘so I am only cruising at around 50 to 60mph – but it’s almost there. I reckon that once it’s run-in, the Trophy will cruise all day at 70mph. I think it should

make the magic ton or, if not, very close.’

So all’s well that ends well, yes? Erm, no. Not quite. The Trophy hasn’t quite touched Jerry’s heart, and his other bikes are more likely to be ridden in future. The TR6 was an impulse buy, and it’s a bike which Jerry’s decided he doesn’t want to keep in the long run. Perhaps Mrs Jerry will get that new bathroom after all!

If this TR6C is your dream bike, then go look in the RealClassic Classifieds and see if it’s still up for grabs.

A sheepish Rowena, caught in the act of standing up on the pegs and making 'brrrm, brrrrm' noises.

Single or twin carb best?
