Re: Keeway Motorcycles yay or nay?
The old Suzuki GSXR's from the 80's were famous oil cooled bikes.
"Some manufacturers use a hybrid cooling method where engine oil is circulated between the engine case and a small radiator. Here the oil doubles as cooling liquid, prompting the name "oil-cooling." Suzuki has produced many oil-cooled motorcycles. Modern BMW R-series flat-twin motorcycles, such as the R1150GS, use air and oil cooling. Polaris's Victory motorcycles use oil/air cooling exclusively."

Yeah, It's a more efficient method of keeping the engine cool than simple fins and heatsinks on air cooled only bikes, as I understand it. Particularly if the bike is likely to spend quite a bit of time in the higher end of the rev range.

Pretty much.Bitte_Kein_Lexus wrote:Haha fair enough, it's an oil cooler or whatever you wan to call it. What's the advantage vs bikes which don't have one?
Slightly better cooling vs standard air cooled bikes, but not as much as a liquid-cooled bike?
It's a dual purpose thing in terms of advantage, the oil cooler allows more cooling surface area so more heat can be dissipated and also increases the oil capacity so that more heat can be absorbed by the oil without breaking down.
There are two main reasons that an oil cooler is used over a water cooled system (in my opinion). First (for a small commuter bike) is cost and ease of installation as there's usually no need to modify an air cooled engine to accept an oil cooler. Two lines off the cylinder head and a cooler, that's all you need. No water pumps, no radiators, pressure caps, extra coolant tank, extra coolant lines etc. and yet, you get some benefit of extra cooling.
The second reason is to get the benefit of extra cooling while saving some weight over a water cooled system, which is why the gixxer and others have gone that route (Ducati, Buell, etc). Again, no water pumps, extra radiator, coolant tank, etc.

Re: Keeway Motorcycles yay or nay?
isn't 1700 about what a new dream costs? seems that if that was the price point the dream would be the more sure choice.

Apples and oranges.
250cc cross purpose light dial sport/tourer in the Keeway.
125cc under-bone frame moped in the dream.
It would depend on A: Intended use and B: Size of end user.
I've never met you OD. You may be of the size that you could ride a dream in comfort, but I have met LS and I think he may be ergonomically challenged on a Honda Dream.

Re: Keeway Motorcycles yay or nay?
Jerry?! Pretty sure you're mistaken. We've never met, unless you've got a different handle elsewhere. I've met a total of three-four users from K440/CEO since signing up as a member in 2009.
Anyways, not to nitpick but the bike is actually a 200cc, not 250. Still, I agree with everything you said. For just cruising around the city, a Wave would be a far better choice (though less overtaking power). The 200 would be fine in the city as it's quite nimble, but it'll also easily take you to the countryside, on dirt roads, to Thailand, etc.

Re: Keeway Motorcycles yay or nay?
Just a small FYI:
Saw that they carry a new bike at the Yamaha dealership near Aeon (any other dealership will also have them). For around $2000, you can get the XTZ125.
The video (on fast-forward to make the bike appear faster, haha) is kind of cool. Well-made at least:
Seems like they're quite popular in the Philippines and South America. The Philippino Yamaha website gives the specs:

I can't imagine a big expat on one, but they offer a simple engine with more off-road capabilities than the leader scooter. Seems like there might be a small market for that here. Maybe...

Re: Keeway Motorcycles yay or nay?
A farm bike is what they are. There's a number of them on a farm nearby my work. Good for trails and bumpy tracks. Light.
Poor quality build at first glance. Shoddy fixtures etc. typical small Yamaha.
