    Nope. The C109RT fuel economy isn't that great anyway at 225 km per a 17 litre tank U better be looking for a gas station.

    It's recommend that you hold the gear a bit longer with these rides. That's why these Bikes really do Suck when used in town.. It's like a Diesel Car or truck. How do you kill a Diesel vehicle. keep it in town.
    These are highway Bikes.
    at 120 Km I still have lots of throttle left to go. I've had my bike up 160km and there's room to still move. on the track at mission raceway in Mission BC 0 - 100 Km per hr takes a mere few seconds only because of the tall gear ratio and quick response of shifting.

    4th gear you can comfortably hold 105 Km per hr. 97 is ok but U can hold 105, this Bike Purrs at 120.Km

    With what I have posted of shifting I fill up every Friday to and from work 5 days roughly 200 Km. I'm happy with that.
    I use 89 Octane. 87 I seem to lose power and sounds like ****. 90 or better and i get a lot of popping when I shift or back off on the throttle. I tried 94 once and I thought my bike was going to explode.. there was so much popping going on.

    Anyway. These are just my findings I'm sure every C109RT is a bit different than mine.

    225 for 17L is bad. I am not sure where u are but in Australia, we get 91,95 and 98 octane fuel and i have always used 98. As i mentioned my gear shift speeds earlier, i get 320kms on full tank and i dont stall my engine either.
    Everyone has different riding style so different mileage.
    All i can say is try riding as per what i said for better mileage. If u dont like it then so be it.

    Suzuki Boulevard C109RT Specs



    Description: The 100-mph Loafer.
    This machine is like your linebacker friend in high school who used to calm people down by reaching over and giving them a quick squeeze on the back of the neck like Spock but with incredible muscles and a beer in his hand.
    The C109RT runs in laconic fashion, with no fuss, and seems to work without really trying while it achieves pretty amazing results. Fast and big rarely coincide when combined with maneuverability when a bike has a tire this wide, but this beast does it, and then some.


    Specs: ENGINE AND TRANSMISSION >>
    Displacement: 1783 cc (108.8 cubic inches)
    Engine type: V2, four-stroke
    Engine details: 54 degree V-twin
    Compression: 10.5:1
    Bore x stroke: 112.0 x 90.5 mm (4.4 x 3.6 inches)
    Valves per cylinder: 4
    Fuel system: Injection. Suzuki Dual Throttle Valve system (SDTV) with 52mm throttle bodies
    Fuel control: DOHC
    Ignition: Electronic
    Lubrication system: Dry sump
    Cooling system: Liquid
    Transmission final drive: Shaft drive (cardan)
    Gears: 5-speed
    Driveline: 5-speed constant mesh
    Exhaust system: 2-into1-into2 stainless steel chromed

    CHASSIS >>
    Frame type: High-tensile double cradle steel.
    Front suspension: Telescopic, coil spring, oil damped
    Front suspension travel: 130 mm (5.1 inches)
    Rear suspension: Link type, coil spring, oil damped
    Front tyre dimensions: 150/80-16
    Rear tyre dimensions: 240/55-16
    Front brakes: Double disc
    Rear brakes: Single disc
    Wheels: Cast alloy

    DIMENSIONS >>
    Seat height: 705 mm (27.8 inches) If adjustable, lowest setting.
    Overall length: 2,580 mm (101.6 inches)
    Overall width: 985 mm (38.8 inches)
    Ground clearance: 135 mm (5.3 inches)
    Wheelbase: 1,755 mm (69.1 inches)
    Fuel capacity: 19.00 litres (5.02 gallons)









    Most people on this form that have talked about fuel economy are getting at Best. 265 Km to a fill. At Best.
    And I did say At 225 U Better B looking for a Gas Station. !
    Your getting 320. that's Amazing ! What's your secret . Do Share.

    I dont have any secrets although my majority riding is on highway between 80 and 130 km/hr speeds. Town riding isn't as much but is around 60km/hr in 4th gear.
    Tyre pressure is as per recommendation.

    1st-gets bike moving from a stop and that's about it. Our transmission doesn't like to upshift from 1st in a high RPM range. I "short shift" out of 1st very often.

    2nd-quick shift from 1st. use in heavy traffic slow speed turns parking lots to about 20 mph

    3rd-back road cruising speeds. 20-40 mph. used a lot on town and back roads. grab 4th for fuel economy

    4th- 35-55 mph. still back road cruising on higher speed limit roads. Can grab 5th if road is flat and your speed is above say 45 mph

    5th- highway cruising.

    Our big cylinders in this engine allow us to lug the RPMs down pretty low in an upper gear before it starts to buck. I tend to utilize this fact around town to keep the bike quiet and save a little gas. When im in the mood for speed and acceleration ill cruise in the lower gear maintaining RPMs for that quick throttle response when I want a lot of raw power.

    The above speed chart is mostly a guess on my part. Ive owned this bike for about 25,000 miles now. I don't watch the speedometer much. I listen to the RPMs of the engine to base my shifting. Those speeds I listed are approximate to use for a beginner to get a handle on what the proper RPMs should sound and feel like. Everyone's bike is a little different with different mods. I have a lot of mods on my engine with Exhaust, intakes, ATRE and a fuel processor. One other fact to note, our speedometers are all high by 10%. If your like me and ride with a GPS on your handle bars you'll notice speeds on the GPS are lower than the gauge on bike. I don't know how fast our bikes really are. I had the factory 109RT windshield and lowers and at 116MPH the handlebars would start to become "squirrely". Lots of pull left in the engine. Ive tried to push thru it only to become a little terrified. I am assuming this is either lift or just unstable air over the windshield. Now I have a Tsukayu fairing with the factory lowers modified to fit. Top speed before the front end starts its death wobble is about 100MPH. I have been dying to remove the fairing and try to see what I can get for top speed with no shield but have yet to try this. Keep in mind my comment about the 10% speedometer issue. At 116 MPH my gauge read 130MPH. GPS was reporting 116MPH. Don't listen to the folks that tell you our bikes do 150mph I don't believe it.

    Talking Shifting Speeds

    I do what works for me. I knew my GPS was lying to me.. I should have been going faster to get away from that cop.. LoL.. I could have done it too.
