Triton #1 May Be Making A Comeback

Aluminum is lighter than cast iron and dissipates heat better. Aluminum cylinders and heads are less likely to develop hot spots compared to cast iron. Aluminum is also way easier to work with for porting and mods that require removing material. Cast iron is usually cheaper and can be honed to make it last longer. The aluminum cylinders use a hard coating on the cylinder walls and I would assume honing would remove too much of it.

As far as the Airsal in particular, it is a single ring kit that reduces friction to make it more efficient at higher revs. It also has some pretty nice porting, like the large bridged exhaust port. The bridge is used to make a larger port possible in 2 strokes. If you made one giant port with no bridge it could cause problems with the piston ring(s).

So it sounds like the aluminum is a more durable product, however you only have one ring. I thought one ring systems were more for race setups.

Side note - I remember reading back that you had a bent handlebar. I do too on my old scoot, same bend as yours. Were you ever able to twist it back? I wanna give it a shot but don't want to break it in the process (fix it til it breaks ).

Actually cast iron is more durable. Aluminum is a better product short term. One ring systems are intended more for race but they can be used on the street. They are more efficient at higher RPM, but less efficient at lower RPM. I know Gordon Jennings (Two Stroke Tuner's Handbook) says that below 7,000RPM a single ring kit would be a disadvantage and above 7,000RPM it would be advantageous. To my understanding, single ring kits are also less durable, making them less desirable for street applications.

My handlebars were bent in a couple different directions and I just replaced them with an aftermarket setup.

Those aftermarket bars are pretty sick looking, man. Definitely worthy of being naked.

They won't look that cool when everything is hooked up. Everyone else strips them down and adds witches in different places to control the lights and gets fancy speedometers and tachs and what not. I use the stock switches because I like everything right at my thumbs for convenience and safety. I just have my bike speedometer because I'm too cheap to buy a Trail Tech or Koso or something like that right now. lol So wires and junk everywhere on mine. The main upside to these is that they do seem to be in a more comfortable position and the quality and rigidity is not even comparable to stock.
