Mmmmm,,,,AVL goodness
Shaft mounted rockers. Quench chamber head. CV carb. Alloy cylinder. Modern Piston. Full roller crank of pressed up construction with forged steel con rod riding on needle roller bearings on a 30 mm crank pin. Cams mounted on adjustable spindles for quieter operation. Gear type oil pumps (pumps over 4x the oil volume of Iron Barrel plunger pumps) Electronic Ignition. The engine was designed and built to cruise at 60-65 all day.
Interestingly the AVL uses the same basic crank case castings as the Iron Barrel engine. With some machine work they could be interchanged.
The 5 speed Iron Barrels and the AVL use the same transmission and clutch.
IIRC the UCE uses the I.B./AVL 5 speed internals but with the shafts stacked vertically instead of horizontally like the I.B. and AVL. BTW parts and service are still available and should be for a long time.
Disc brake kits are available last time I checked. I think it is a worthwhile mod.
I own and ride and Iron Barrel and can report that my drum brakes are indeed adequate within its envelope.
I have test ridden a UCE and can report that the front disc brake on them is a definite improvement over the drum brakes. The disc set up offers a better lever feel, shorter stopping distance and are fade free.
Since the Bullet in the pics is an AVL Classic (A.K.A. AVL Bullet) and not and ElectraX, all the accessories ( other than engine parts ) for an Iron Barrel Bullet will bolt right on.
