Classically exposed: the Yamaha TX 750 (1973-1974)

Holiday content banner

A piece of work from the time when the Japanese still thought they were defeating the English motorcycle industry with their own weapons. Yamaha invented the Yamaha TX 750. A beautiful motorcycle with a wonderful character. And it was so English inspired it was just as unreliable as a British bicycle. Oops: Just kidding…

To prevent the 750 cc parallel win from vibrating just like an English engine, Japanese engineers fitted it with rotating balance shafts, the. “Omni-Phase balancer” In practice, those useful lumps of metal spun through the engine oil, creating a frothy mass. Greasy air is not enough to lubricate an engine block. Oh, yes: the chain of the balancing system stretched, causing them to vibrate. Add to that the fact that there was still some nice gas in the time of the XT and of a long speed, the XT was not happy with that either.

The balance pipe directly against the cylinder head was less successful than optically in terms of cooling. The factory came with a compensation arrangement, warranty and a modification set. Fitters from Japan were even flown in to repair the image damage.

But the suffering was over: the name TX was contaminated and the wonderfully designed and wonderfully sounding twins made a free fall in terms of market value. Later tests showed that such a TX with modern motor oil specially developed for motorcycles would have been problem-free.

With its critical technique, the TX was just one step ahead of the then oil technology.

And all those TXsen who died too early? They had often driven so few miles that they were put aside gloomily in the expectation of better times. So there are quite a few left over. They are now starting to find their owners again. Now they will no longer be filled with youthful hotheads with testosterone tuning. They are allowed to do what they are made for: touring quietly and stylishly. And make you very, very happy.

The TX750 now. A beautiful TX 750 is a desirable possession. A style icon, an ode to earlier days. See every copy that is less than fine exclusively as a donor bike. Parts for an engine that has only been produced for two years are about as scarce as virginity in a brothel or honesty in politics.

Therefore, buy immediately if NOS (new old stock) shows up somewhere. If you do not need the spare parts yourself, then it is the mirrors that you can exchange for beads with your fellow TX adepts. Because in such fraternities it applies that 'together we have and know almost everything'. And oh yes: in the short running time of the TX, quite a few modifications have been made in terms of engine technology. So first check very carefully whether all the things you are going to screw together are friends. And the valve clearance on a cold block is only 0,05mm.
American import models, and indeed, sometimes you find one, are often not modified. The real Europeans are that for 99%

A few years ago there was / were someone in NL who bought as many TXs as they could. Wondering what happened to that ...

  1. Nice story Dolf, I had an orange TX and my buddy a green one. I got stuck in the Pyrinees, luckily on the way back. In Perpignan I put the motorbike on the train to Amsterdam and I also took the train home. Heavily damaged in Amsterdam, received again after 2 weeks [He was missing]. Then traded it in for a green Honda CB500cc 4 cylinder. At Okkel Moeke in Heemstede. If only I still had that TX. [And that CB500]. I'm now working -in my shed- making a cafe racer from a withered 750 Yamaha Virago 1983. Good luck Dolf.

  2. Good story, I just bought one to make it drivable again. Fortunately I get help and information from a bunch of TX enthusiasts who also hold a TX meeting every year. A challenge to make something beautiful out of it, but that is also the pleasure of working on old engines. In any case, I will be back under the roof from winter.

Why don't the trains run on time?

Who will save this “ONK” VW 1300 from 1969?
