Thanks for posting this TheBear. That 2stroke sounds so pissed off with the world!

Was that a 4T that blitzed it at about 8:30? .............................  :pot:

Yes, how is that possible?  A tuned 1000cc 4T with a 6 speed box, made 30 years after the TZ750.... :peepwall:

It could be, especially since this footage is from a practice session for the 2017 TT Classic. 

Ekt ook nogals gewonder hoekom daai voorste bike ni weer ingehaal word ni?

Soos gesÍ, die was tydens oefening vir die TT Classic so ons het geen ideŽ wie die bikes ry nie.  DIe een kan 60 jarige Oom John van die Isle of Man wees wat 'n 35 jaar oue 2t Yamaha het vir sy persoonlike plesier, terwyl die ander een deur John McGuiness of Michael Dunlop gery word.

Note to self; Cracker is a communist millenial.   :thumleft: :thumleft:

I read a very interesting article in a magazine, where they pitted Suzuki"s 1973 TR750 and Yamaha's 1981 TZ750 against Superbikes of around 2000, and already the TR was outraced, or more precisely,

outhandled, and the TZ showed considerably better, marginally beating the 1000 4 cylinder superbikes.

In the TT, against modern tuned 1000cc 4strokes, a TZ750 would have no chance, in fact it would be quite a lot slower.

But nevertheless, that TZ needs not feel embarrassed at all, against a hot 4stroke, a quarter size bigger, and 40 years younger. :ricky:

You could actually see on the video that the TZ had a good rider on board, but often the bikes collectability would urge caution, although it did not look like it. :ricky:

But this 40 year old TZ750 would have zero chance against a 2017 superbike.

The TZ750 was designed for 'proper' short circuit racing and was hardly the kind of machine on which most riders would care to push the limits on a narrow and bumpy circuit like the Island without run off areas and gravel traps.

Could it be that a rider on a bike from a more modern era, with vastly superior frame, brakes, suspension, and no doubt features like traction control, steering and damping electronics etc,
simply felt more confident to overtake?

a third bigger.

But remmeber this model was an out and out racing model.

That was the best endurance race I ever saw, after 24 hours the Team of Chemarin and Leon won the Bol d'Or but that after fighting with Pons and Saron (both 500GP riders) on their OW31 (TZ750) Yamaha until about 9 in the morning but the Yamaha 2 smoke lead for most of the way, till it blew the engine!
The yammie was faster but had to stop more frequent for juice. What a pitty it did not make it to the end! What a sound every round!

Look at the equipment, helmets, pit crew and the posture of the riders!

Will never forget that weekend!

Endurance racing was my cup of tea those days and travelled to all the races around Europe!

Just picked up on this and really enjoyed it.The TZ was a monster of a smoker and the boys who raced them weren't poster boy sponsor puppys ( or maybe the were ! ).The power and character  of those 2 smokes mostly left the frames behind 😉 Sure,the modern day 4 stroke gazillion dollar missiles will blast them on any Sunday.......but lack the smell, sound and rogueness of the era smokers 😁

Johan Boshoff, died on one of these OW31's on Kyalami in 1977.  That thing was vicious, but a sight to behold in full cry on a race track.

I never missed a race with him on that big TZ. As well as Dirk do Plooy on his "pork chop" TZ750.

It is an oft-repeated cliche, but you could not have lived if you have not heard a TZ750 at full cry on a overcast Cape raceday. My God.

what sticks in my memory as much as the sound was the smell of burnt Castrol racing 2 stroke oil.
There's nothing that beats the smell of 2 smoke in the morning... ;D

Not just the frames, the tyres were left way behind by these engine developments, tyres have seen the biggest technical advances of all in recent decades.  :sip:

Oi!  Oom John from the Isle of Man would donner me if I insinuated he was anything but a good rider.  He is just not an IoM TT winner anymore.

Which year was that?

Maybe 1980, the REA Racing TZ750? I was supposed to be there that year spectating but was broke as usual.  ::)
