I was thinking the same thing. Looks like you get just as much oomph with the 103HO as the 110.

 

Yep, here's a graph on a 2010 se110

Wow thats disapointing, less than the air cooled you guys tested a while back. Granted dyno could have been off on either or by a tad but they are basically the same so this sort of debunks the liquid would be better for performance. All the liquid cooled is going to do is lower the temps a tad but other than that waste of money and looks it seems.

 

Agreed. That's terrible.

 

Compare the shape of the curve?

 

I would like to see the 110" with a set of slip ons only,just like you did with the 103".

 

Wonder how much weight the water set up adds?

 

It would be minimal. As it sits it is one kg. 2.2 lbs heavier than last years bike.

 

According to the HD website, the weight difference between the Ultra Classic and Ultra Limited is only 17 lbs, so it can't be very much.

 

It should be noted that the amount of liquid cooling being used is ridiculously small.....just one passage around the exhaust valve. The real benefits of water cooling are seen on an engine that is COMPLETELY water cooled.
