sorry about the typos; web-based inpuit can't keep up with my modest typing speed....

Thank you for the replies how would this compare to my 1946 350 Model G ?

Thanxs for the valuable motor reminders. Am aware of the A65 oil pressure
bearing failings, and for that matter, have had a well worn pre-unit T100
Downunder in the fifties that sure rattled good. Besides the bikini fender,
'bike has the nacelle and larger front mudguard. Those post war Iron 350s
were quite numerous in Queensland in the same period. Sorry, Red, would
prefer either Triumph to the model G, although a bird in the hand beats
dreaming, and have empathy you keeping it

Reds, you can't really compare the two bikes. The 3TA is a twin and that makes it very different IMO.

[simon]

Not an expert on either model admittedly but surely if a 3TA is producing 20bhp it would eat a Model G for breakfast?

[Presto]

It’s true the 3TA and the Model G are different, one a twin and one a single, but they are both of similar eras and both are 350’s. I’d say that the Triumph is years ahead of the Model G in engine design and sophistication, and, IMHO, in aesthetics too. I guess weight is similar and so too would be seat height, if that matters. But for steering and road-holding maybe the Model G is ahead, although on both bikes their soft performance isn’t going to be very challenging in this department. For mechanical simplicity the Model G wins out. For parts availability I guess they are close, maybe the RE gets more points here because the parts are likely to be less costly and supplied from a company that has no equal for service!

The 3TA was a quite soft engine with a comparatively low CT but it quite easily be tuned to Tiger 90 specs which was quite a bit more sprightly.

The 3TA (aka Twenty One) was the first unit construction Triumph. 1959 is an early one and all things being equal might be worth more in the UK because it requires no MOT, so is cheaper to run, though a buyer will need to check a pre-1960 bike more thoroughly unless the owner has had an MOT done before sale, though it has to be said that not all MOT certificates are worth the paper they are written on. Re tuning IMHO the less tuned bikes are always sweeter. A 350cc Triumph is never going to be a quick bike anyway, but will be easier to start than a 350cc single because you're only kicking a 175cc cylinder to start. Like I said, I think these bikes are going to become pretty popular with older riders....

Older riders?, I bought a 1964 Tiger 90 around 30 years ago I don't ride it as much as I should, too many bikes, but I love that bike and it will be the last one to be sold, older rider, yes.

Tuning a 3TA to the same spec? Not that easy I am afraid,correct T90 pistons are like hens teeth, the cams are different, the head/valves are different.

Cylinder number and aesthetics aside Roy Bacon has the Model G at 15bhp, if as previously stated in this thread the 3TA has 20bhp then I know where I which I would choose in a race.
