I mean it's a very pretty machine. It's kinda like dating a beautiful partner that has the voice of a cat that's had its tail stood on. It'll be fine as long as you don't start and run it.

I probably won’t start it very often. This bike was designed for a 17 year old weighing 62 kilos and not a 70 year old weighing 81 kilos. The riding position does not allow for my pot belly. The TZR was the most expensive of those type of bikes although, in my opinion, the Honda NSR was the best looking. Wish I had one of those.

I think Ed's starting to weaken.
It could be the meds kicking in.

I personally think he's had a visitation from the Two Stroke Ghost of Past, he woke up all shivery and smelling of Castrol R.

Mmmmm, castrol R and methanol. Gorgeous.

I think in Ed’s eyes this bike is fine but the main complaints come from his ears and nose. Don’t bring Brexit into this Ian, my sons live in Germany and think all non electric vehicles should be banished whilst their chosen country burns more coal than any other EU country to power their non polluting electric cars. They also seem to think it’s right to hold up the English (non Europeans ) as much as possible at passport control whilst the Americans and Chinese are welcome to use the digital passport readers. It appears to me that it’s only the English that have to pass through the “non European “ section. Still, as you say Up’t we’re as good as back in now but without any of the advantages.

I have no issues with the visuals of any 2 strokes as they look like, well, motorcycles. My problem lies is the vague hit and miss nature of the air-fuel mixture and exhaust gasses passage through the system. At least in a marine diesel 2 stroke engine the flows are properly managed, with a motorcycle 2 stroke it's more like "some of the gasses will do what they're supposed to do". Plus the lack of proper lubrication - again not a problem with marine 2 strokers.
Oh, and the noise!

Marine diesel two strokes, now that’s an interesting/boring subject depending on who you are. Does the Yamaha reverse cylinder 2 stroke engine cure any of those flow issues that you mention Ed?

Ren - The Ed¹ said :-
Glyn - NO!
Marine 2 stroke diesels as fitted in some large ships have
a) A very large turbo or supercharger. This keeps a positive pressure around the base of the cylinder where the inlet ports are - ensuring that the fresh air charge (no fuel, that is directly injected) comes into the cylinder and not returning exhaust gases.
b) The inlet ports are around the base of the cylinder - separate from the crankcase and underside of the piston allowing proper pressurised lubrication of the crank and small ends
c) An actual exhaust port much like a 4 stroke.
d) Direct injection rather than mixing fuel with air, lobbing it into the crankcase and seeing if any of it reaches the combustion chamber.
Now I seem to recall that someone like KTM did a direct injection motorcycle 2 stroke. Better, but not much. If that could be combined with a forced air intake like a blower then better... but ram-air pressures are at best just a marketing feature.

You might think your welding is bad. Here's my attempt. In its favour it is at least strong.

Just read a review of the latest Triumph Scrambler 400X, seems like a nice bike for dirty muddy gravel road work, however what is it with the "Upside down Big Piston forks? I'm aware it's something to do with less unsprung weight? But why put the fork slider tube down where all the dirt is! Having two bikes with "right way up" forks and both of these have rusty bits on the forks, the Inazuma because the chrome layer is too thin and the Bandit because its a bit old and used to live in a damp shed with the previous owner I can see that a properly used 400X is going to keep the Triumph dealers in business with fork repairs! I can get Inazuma fork tubes from China for £50 so not too worried about sorting the Inazuma. Most Inazumas in NZ suffer from fork rot to varying degrees but they are 6 to 11 years old now. I presume with your salted roads the problem would be worse there? I presume the 400X is just fashion over function?!

The short answer is fashion. Like some sports bikes now have aerofoils / spoilers on the fairings. Totally pointless.

I saw the 400x recently in a German dealers showroom. The bike looks great and at a very reasonable price too. Then I looked a little closer and was sorry to see a single cylinder although the engine actually looks like an early Triumph twin. The same old problem for me was the high seat. The salesman said it had put a lot of potential buyers off.

Ian Soady¹ said :-
High seats - another fashion "statement". I fail to see why we need such a huge gap between the back wheel and the mudguard to cope with - on a road bike - 6" or so of travel. It just makes those of us who are less flexible walk straight past what otherwise may be decent bikes. Although I'm not and have never been in the market for a new machine.
And what's wrong with singles?

Out getting some steps in today and saw this in a ditch. I’m sure it’s a Honda of some sort but there was no decals or badges in sight. I don’t think I need this one although I was seriously tempted to find the owner for at least 5 minutes.

That, my friend, is a Honda CMX250 Rebel (or possibly the 125 version).
233cc (or 124) parallel twin with a 360 degree crank (pistons go up and down together, even firing sequence, bad balance). Based on the CD200 Benly motor which is a very strong motor. Single carburettor with a manifold. AND AND AND it's a 4 - FOUR stroke.
It is a WONDERFUL machine. After my little crash I couldn't bend my knee much so this was my first bike after the smash. I loved it dearly and would have another in a heartbeat... if I had the room.

Looking at the image again I might be seeing the remnants of an "L" plate behind the front mudguard? If so it will obviously be the 125 version.

Glyn said :-
You are reliably correct again Ed. After a little more research I find that it is a 125cc registered with a P prefix on the number plate that makes it 1997 ish. It’s a little along the style lines of the Yamaha 125 Dragstar which was probably the competition at the time.
