That's very good indeed. I think the Burgman is one of the best mid size scooters for fuel efficiency and performance.I push my "Wife's' 400 as hard as I can when I ride it. We live at 7000 Ft and I still get 56 to 58 mpg average city/highway. It's a fun bike to ride and at that kind of mileage, just enjoy the ride. The smiles per gallon can't be beat.
"Ride more Worry Less". Life is to short to sweat the small stuff!
I had not thought about it but you're right. l live in the mountains and most of my riding is crooked mountain roads. I had a 08 400 last summer and riding hard on crooked mountain roads averaged 68 MPG and interstate riding dropped it to just under 60. I rode it 4,000+ miles before the 83 year old guy totaled it when he hit me in the rear.My best mileage, believe it or not, is riding twisties. Sure I'm flogging it uphill, but there's little gas used on the downhill. Considering the average speed is 40 mph, I get almost 70 mpg. So I'd agree with Chip, 40-45 mph gives the best mileage.
But mine is completely worn in stock bike. Swoopy, albeit buffeting, windscreen and all. I like it!
This is mostly due to the added wind resistance on the burgman. Was looking at my reflection last time I rode and realized that my back was creating a huge vacuum behind it.I still can't believe the Jetta weighing 6x the Burgman gets better fuel mileage at certain speeds with a motor 3x the size. Best mileage with the Burgman has been just under 50mpg. Overall mileage of in town and out with the Jetta runs around 39-42mpg. Since it only has 3500 miles on it and most of those were winter driving it should improve some in warmer weather and as the running gear fully breaks in.
Nothing done to the CVT will affect the engine's output, or for any practical consideration impact the CVT's efficiency--which is not all that great. The few Burgman 400 dyno charts I have seen show the rwHP (rear wheel HP) at 24 to 26, Suzuki claims 34 fwHP (flywheel HP).Thanks Cliff, that is a great response. I think you nailed it. My only question is if the sliders would make any difference at all? If the most efficient RPM's are coincident with torque peak, wouldn't the most efficient rpm remain a constant irregardless of what is going on with the CVT? Or do CVT modifications impact peak torque?
