Question I thought the fuel mileage on the RC was bad enough already.

I understand that the 2002 RC-51's have even bigger throttle bodies than the previous year models,54mm-62mm. I get about 28-30 MPG, my cage gets 32MPG, and I thought this was horrible for a motorcycle. I was wondering how many 2002 owners out there are getting Gallons Per Mile...instead of Miles Per Gallon! The latest edition of Sport Rider stated 28-35 with 32 on the average. I find this very hard to believe Please give me some real world numbers.

Well lets see...4.8 gallon tank....subtract 1.2 gallon reserve.....100miles divided by 3.6 gallons= 27.777

I know horsepower costs fuel, but both of my GSXR-750's got close to 40MPG and they aren't exactly slugs. What about gearing or combustion chamber design; do V-twins simply use more fuel because "That is the nature of the beast," when compared to inline 4's

I don't think so as my 98ZX9R gets about the same. Although Kawasaki's have always been known for getting lower gas mileage.

Thumbs up

It's in the design............In-lines are far more fuel efficient than the V's. Look at it this way. Which gets the better gas mileage...........A Honda Civic 1.5 OR a Chevy Camaro L-88?

Lightbulb What about displacement?

I would agree with you if you could give a more realistic example. You are not comparing apples to apples. Of course a 1.5liter engine uses less gas than a 5.7 liter That is like comparing a M1A2 Abrams tank, 5 gallons just to start the damn thing, to a 5hp lawn mower. Can you clarify "Design" based on similar displacements.

Unfortunately..................There were not too many V's that were in production except for the Mopar 262, 283, 292 that would be close enough in displacement.

But my original I stand by because of the following reasons. Like the L-88 the RC51 produces the torque disparity and as the L-88 drinks that much more fuel than the 1.5, so does the RC51 compared to the In-lines.

Example: RC-51 @ 27mpg, CBR600F3/4 @50+mpg, GSX-R750/1000 @ 40mpg....ETC..

Meaning, at the low end of the scale the fuel efficiency is that of 12mpg less than the "production" In-lines and at the upper end of the scale, a 23+mpg "diparity".

I LOVE FAST!

Ouch!

Thats crazy bad gas mileage. On my cbr 900 I got close to 60mpg on a 8 hour trip and as a daily driver to and from work I get close to 50mpg.. But I do almsot all highway driving at 70mph. None of this stop and go stuff.
