The CB1100 Community Forum

I had a 2013 CB1100 I bought used with a Dart classic flyscreen. I didn't really care for how it looked, but was too lazy to remove it. I averaged a calculated 53 MPG over 9K miles with that bike. Last June they were practically giving away left-over 2014's, so I sold my 2013 and bought a 2014. I was disappointed to see that the 2014 was only averaging a calculated 50 MPG for the first 4K miles, even with a 6th gear. On Saturday I installed a Dart classic flyscreen on the 2014 and was astounded to see my calculated MPG jump from 50-51 to 55-56 MPG. The computer MPG shows a similar (but inflated) jump.

Has anyone else experienced this MPG boost after installing a windscreen? There must be a lot of turbulence created by the instrument cluster.

yea it makes sense that you smooth out the wind flow and your mpg goes up. That's a good deal, the Dart will eventually pay for itself.

Just my opinion, but the Dart Marlin is maybe effective up to 120 km/h (possibly less on gusty days). Nevertheless, it does reduce wind blast on the chest.

I have a Dart Marlin, but haven't done any calculations with gas mileage.
Maybe it helps, but I just ride
