setting the pace for lightweight & big bore thumpers of recent. the duc M1100 is 373 lbs (wet i think) in 2009. the buell 1125 is around 390 dry. i wonder if the M1100 could strip off 50-60 lbs for a track. awesomeness. and probably an inspiration for mr. buell. what a foolish move to remove the very good buell line. one of the best realizations of american engineering. considering the amount of bailout money given to those losers at gm, ford and other useless engineers. cripes. perhaps the chinese will bailout buell. i wouldnt be suprised.

Dan R,

Basic H-D engine recognition stuff worth learning:

You might want to compare Sportster cam covers to BT cam covers. How many Sportsters have 2 lifters in the same lifter block – and at different angles from each other rather than parallel like Sportster pushrods? How many Sportsters have bolt on primary drives & transmissions (Hint: none)? Why is the oil pump behind the cam (BT style) rather than underneath them (Sportster style) ? Etc..

And NO, BT pushrods don’t cross each other.

Sorry guys. Look at the pushrods. A big twin has crossed pushrods. Sportster pushrods are more parallel. At 1232cc it is a juiced sporty. But STILL an awesome bike!

That looks like a mid-80’s Honda Hawk NT650 frame.
