43 MPG ###

43 MPG (18.3 km/l)

That's what I am getting.

New exhaust
Fresh oil
New air filter
New tires
Fresh final gear oil
GIVI 214DT Wind Screen (Amazing BTW)

What are you guys getting?

Did I mention I love driving this thing?

While a few months old now my setup look’s pretty close to yours. Bike is a 2004 with 58k (km) on the clock. I mainly drive for fun/leisure and get around 14.5-15 km/l. Should say that my 160 kilo takes its toll on the fuel consumption but admittedly I also like feeling the acceleration…

A steady throttle hand is the key to better fuel economy. At this point, like young Mr. Benzon, I ride mainly for fun/leisure. But “around town” with too much stop & go I get mid to high 40’s; last weekends nice leisurely ride out to Amish/Mennonite country got me low to mid 50’s; and on two occasions (unencumbered, mostly Interstate miles) I’ve gotten over 200 miles on a full tank.

Thanks guys. I don't feel too bad then. I put a LOT of throttle into it to get my 270 lbs. (hardly any muscle ) scooting down the road. And I love to go fast even between stoplights.

I may try one tank in full conservative mode, slow steady acceleration, 65mph on the freeway and steady speed. Steady speeds are MUCH easier with my new "Crampbuster".  

But at least I know I don't need to go searching for some fuel robbing gremlin. It's all at the end of my right sleeve I believe.

Slow hand and smooth throttle will get you into the 50 plus MPG range. Hills and headwinds pull it down.
I average 50-55 in the warmer temps. and don't ride at a slow pace.  24G sliders it pulls hard away from stops and still gets good MPG. Delkevic muffler sounds nice not too loud I have a similar one.

I still have notebooks from when I used to compile fuel consumption stats after every fill up. Then I skipped doing it a couple of times and that broke the habit for good. After that I just jotted down random mpg notes down on touring trips, or if I was just plain curious about fuel economy.


With my 2010 Silver Wing I'd normally get 55-58 mpg doing local rides, that's about 10 mpg less in US gallons.  On long rides where I'd normally ride at least 150 miles between fill ups, I'd get 65-68 mpg in our Imperial gallons, again 10mpg less converted to US gallons.

Another weird thing is that petrol/gas has been sold in litres in the UK for many years, but we still convert it back to mpg because we still have a miles per gallon mindset.

With my Forza 300 I've only worked out mpg figures once in the early days and I was getting 93 mpg. One of these days I may get round to changing the Forza's fuel consumption display from l/100km to mpg, although it's enough knowing I can get 200 miles range from it's 3.04 gallon (3.65 gallon US) tank before reserve kicks in.  

The UK changed over from Unleaded to the dreaded E10 ethanol fuel last September. After using it for the last six months I've now no issues whatsoever with E10, it's pretty much the same as Unleaded.

My 2012 has always been pretty frugal for a scooter that tops 500 lbs. I drive conservative for the most part and land in the low to mid 50's for MPG. (US figures) On several instances I have topped 60 miles per gallon which throws me way over 200 miles to a tank. My SWing has 28 gram DR sliders but noticed no major diff in fuel usage over stock rollers.

My 2015 Forza generally hits 75 MPG steadily but is susceptible to the wind and hills (smaller displacement) and it drops quite a bit. Down to high 50's or low 60's.

It's interesting that the 2018 Forza 300 I have weighs in 100 lbs lighter than the previous version.

According to my specs. The 2015 NSS300 weighs in at 422 and 428 with ABS as opposed to the new version at 401 pounds.  Now the Forza is easily over 100 pounds less than the Silver Wing, which if memory serves hits 550 pounds.

I need to find out what and where "sliders" are. I am fairly happy with my CVT as is. Maybe lacking some power transfer in the mid range.

Have a look in this video - it should help:

Thanks Mike! Reminds me of my old 3.5 HP mini-bike.

So I did some research and I'm going to try Dr. Pulley 28X20 Sliders. There is some debate over the 26 vs the 28's but it escapes me at the moment why I opted for 28.

Regardless, it will give me a chance to get in there and clean stuff out.

I'm probably gonna have to do some of this stuff to the Reflex (NSS250) so it's starting to eat into my mad money pretty severely.

Just got back from a nice ride on the back roads from Lake Stevens to Monroe. Fun stuff!

Not sure if it's the new exhaust or the "CrampBuster". I suspect the CrampBuster. No change in driving habits and am now at 45.8 MPG (6.17 Liters per 100 km).

I tracked my last 18 tankful's of fuel last riding season.  65% secondary (2 lane) highways, 5% multi lane superslab highways and 30% urban roads. My results:

Average around 4.3L/100km. 
= 54.75 US mpg
= 65.75 Imp. mpg
= 23.5 km/L
Max. tank range averaged 377km or 234 miles (calculated arithmetically).  Worst tank = 350 km. / best tank = 404 kms.

My 2009 SWing gets better mileage than my 2005 did.

"My 2009 SWing gets better mileage than my 2005 did." it should 05 is open vs 09 is close loop Fuel injection.

BOT my 2012 with fairly fresh serviced everything !! and only mods being Gboost belt and Malossi white torque spring(no DRP sliders), gets 52-56mpg, avg 54, mostly rural/county roads, but never seen less than 50 even when I ride in town/aggressively, no trunk, etc. BTW not a lightweight either about 230ish lbs in gear !! I use strickly non-ethanol fuel, keep my tires at highest pressure and blow out cvt at every oil change.

I just couldn’t help thinking that you guys must be having the eternal tailwind - or simply fart too much. I’m really impressed with your fuel economy.

I will certainly have another check on the tire pressure. Might be running too low given my weight.

What are you getting? I'm at about 46 MPG however I am fairly aggressive with the throttle.

 I just got my new dr. Pulley 28 gram sliders. Hopefully get them installed this weekend

 Later today, taking my motorcycle driving test. Wish me luck.

37.6 MPG - at best.

Good luck with the test

Well, how'd ya do on your riding test?

Well, it was tricky, and there were lots of tight turns. Slow maneuvers. Thought for sure I’d washed out after putting my foot down on the first two exercises and out of bounds on the second. Turned out I still passed and wasn’t even the worst score. She (upbeat gal from Czech Rep.) subtracted 9 points (3 for each issue). Not sure how many possible.

I was surprised on how many slow, very tight maneuvers were required. I think I will take the 250 for the final. We have two written and two driving tests.

There were 15 people testing with all kinds of bikes, scooters and groms. Everybody passed, even a guy on a huge Suzuki M109 that got -15 and another on a Gold Wing that got -11.

The last time I took the test, I was living in Washington State. Had let my license lapse so had to reapply etc. and take the driving test. I took the test on a Honda Trail 90 that I had at the time; easy to load in my truck and go to the test site. There were about 10-12 people and one guy had failed 3 times already... The examiner scoffed at my using the Trail 90 and said a Harley would do better? He actually said that. Anyway I went through the course and ended with a near perfect score! Take THAT!!! LOL

Glad you made it OK, happy riding.

Slow tight turns ... well of course!  Anybody can head down the street doing 50kph/30mph ... to go slowly and be in control, you have to have a basic degree of know-how.

Congrats so far!

I found it interesting that parts of the course were actually more narrow than sidewalks. I mostly try to avoid driving on sidewalks. What are they trying to teach me here?

Seriously, it does require some balance. Obviously, the bigger bikes had tougher go if it. The SWing felt like a big pig next to those tiny Groms.
