Fuel Economy and Mileage

What 1995-2005 motorcycles have the best gas mileage?

Generally speaking, the smaller the engine, the better the mileage.

Most common fault for poor fuel consumption is dirty air filters, an aggressive hand & and bad riding practices. Fuel consumption is like asking how long a piece of string is. It all boils down to how hard you accelerate, how much stop & staring you do, how much highway work you do. Bike have advanced so much these last few years there's nor much in them at all. There all getting lighter, faster & more advanced.

If you are after a bike for cheaper transport beware. They require more servicing mostly every 6000km, depending where you live air filters every 12000km. Bikes all vary, 750 & 1000CC injected bikes are probably the best. Fitting a power commander is a good example as you are able to remap these. Leaning the bike off in areas needed and richening them where needed. Every bike is different in their requirement. Your best bet is to just get out there and find a bike you feel comfortable on, you feel you can handle (not going to kill yourself on). One that just feels right. Every one is different, everyone handles different. Decide what type of riding you want to do and look for the model that suits your needs.

Other answers from contributors:
  • It seems that a lot of 2-stroke bikes have really good mileage but you do have to take into account that they use a little bit of the 2-stroke oil as well.
  • 4 strokes get much better mileage than two strokes. Ask any outboard motor owner. The fewer cylinders often the better the mileage. The lower the RPM's the better the mileage. Harleys get an amazing 50 MPG's. Low RPM's, only two cylinders only about 45 horse power. Buy a 125cc or a 250cc single cyl. 4 stroke and you will get 60-90 miles per gallon. A 100 Horse Power 6 cylinder goldwing expect about 32 MPG's. The best may be the new 4 stroke scooters. They have excellent aerodynamics. A 250cc scooter that will go 100 MPH can get 80 MPG (not running at 100 MPH).
  • I have a goldwing 1800 and for being one of the biggest bikes on the market, it gets more than 32 MPG. Try more around 39 to 45. Maybe 35 if your riding real hard.
  • I own an 2004 wing and routinely get 38 mpg at 85 mph. (90 - 95 mph gets 36 mpg). Since gas broke $3.00 I am trying to keep it under 2200 rpm in town (not hard to do). My first 200 miles yielded 44.4 mpg and 80 of those miles were at 65 miles per hour and 2700 rpm. I expect to get 45 - 46 mpg in town just by obeying posted speed limits and not accelerating fiercely. This is good on a machine weighing 750 and will cruise cross county! Remember - tires are $125 - $140 each and last about 12000 miles.
  • My Honda Reflex (maxi-scooter) with a 250cc Engine has averaged 68 mpg (for the first 12,000 miles). This is a "twist and go" but it will go about 75-80 mph (actual) and will cruise at 70 all day with no problem. Some report better mileage.
  • Kawi Eliminator 125 - 110mpg
  • I have a 2004 Harley Davidson 883 Sportster Standard. I routinely get 52mpg and have hit 59mpg. The worst was about 47mpg. It only has a 3.3 gallon tank, so the range between fill ups is about 100 to 130 miles, if you don't want to hit reserve. They do have a 4.5 gallon tank you can replace it with, though.
  • 02-05 Honda VFR 800's reportedly get between 30 and 55 depending on throttle usage and, apparently, even the individual bike. This is a v-4 with vtec valving. Smaller displacement single cylinder four-strokes will of course be your best bet for pure mileage, however 400cc is your legal highway limit, and they won't always have the get-up to put you in the safest riding position.
  • My 2003 Honda "silverwing" (600 scooter, centrifical clutch, cvt) seems to deliver around 46 city or highway. I do tend to use too much throttle in town and cruise at 80+ on the interstate. One of these days I intend to do a couple tankfuls at 65mph, but just haven't been able to hold her down yet. I'll post the results if I accomplish that.
  • I find it hard to believe that the BMW F650 is not listed here. I guess what I am looking for is to find the bike with the best size to mpg ratio. It is pretty easy for a 250 scooter to get 80 mpg but my buddies BMW F650 averages 68 and 70+ mpg on the highway. Now the Suzuki 650 DL v-strom only gets 56 on the highway. My little Suzuki DR350 and Ninja 250 both only got 54 on average. I am yet to find a bike that can easily cruse at highway speeds and get better gas mileage than the BMW F650
  • 400cc is not the minimum for highway. 125cc is all for Michigan. I have owned over 60 bikes. A 250cc single cyl 4 stroke may be the best bike for MPG's with enough speed to keep up with traffic. My Honda NX250 conisitantly got 85 MPG's and I am 6'4" 250 lbs. In addition it would go 85MPH. I agree with the previous statement the 250cc 4 stroke scooters are the best MPGs with enough power to be safe.
  • The BMW F650 does seem to be the hands down winner for a freeway capable, high mpg bike.
  • And California rules state: M2 license up to 125cc. M1 license above 125cc. And 250cc minimum for freeways. My 86 Honda Elite 250 had 70mpg at 50 to 60mph and occasionally was pushed to 70 mph. It complained bitterly afterwards. But it was worth it to pass cars in the fast lane on a scooter.
  • I have a 650-CS (Scarver). Riding in Central Colorado and Utah, between 65 and 75 mpg I average around 62 mpg. I find that downshifting and otherwise unnecessarily goosing the throttle (twist grip) can reduce my mileage by 20-30%. I had a Yamaha 250 which got better mileage but didn't have the power to handle the bigger hills and headwinds without winding out in a lower gear. The Scarver with its anti lock brakes and great suspension is probably the safest bike around.

How much oil does a 110cc four wheeler use?

Depending on the manufacturer, the average 110cc engine requires approximately 1 US quart of oil.

Cars & Vehicles
Miscellaneous Vehicles

How many cc 16 horsepower have?

Truth be told you cannot estimate the CC of an engine based on the output horsepower. There are many types or engines!

To list some

Rotary engines - Generally speaking for their CC they are high powered but less fuel efficient

2 stroke engines - Simple in design and leak oil in the fuel system

4 stroke engines - the norm in car engines but there are further classifications

- Undersquared (short stroke - high RPM = High HP output on high revs)

Boxer or square ( Sporty)

Long stroked (better Torque in low revs - low rev limit)

Petrol, Diesel, Electric or Gas?

Fuel distribution technology used (carburator, direct injection, multipoint injection)

Turbo or atmospheric?

The engine's compression ratio?

As you can see the variables are too many for anyone to safely determine the CC from peak horspower alone.

Assuming however it is an electric generator running on petrol it must be less than 500cc but it can vary wildly between 100cc to 500cc

Brakes and Tires

What is the average motorcycle tire size?

The average tire size is a 24 inch tire,and 8inchs wide.

Generally classified as about 17 inches by 3 wide, the curvature (profile) may result in it being wider with a shallower curvature for mor power and sporting grip on higher performance machines.

Can you get your dirt bike engine wet?

Yes, you can't completely submerge it in water, while your riding it, but you can get it wet, when it rains, or when your washing it, or on a trail when riding.. But don't stick it completely into water while your riding..


Who invented the motorbike?

German, Gottlieb Daimler invented the first gas-engined motorcycle in 1885.

These "motorcycles" were ordinary pedal bikes with small steam engines on the FRONT tire...thankfully the internal combustion engine was developed in Germany in 1876 then spawned the Motorcycle in 1885

Kawasaki Motorcycles

How do you chabge the oil on a Kawasaki vulcan 1500?

First remove the drain plug (17mm wrench required) on the bottom of the motor, allow all oil to escape. Once the oil has been removed inspect the crush washer on the drain plug, if it appears damaged replace it, otherwise re-insert the plug and tighten snugly but do not over tighten. Next, locate the oil filter on the rear of the motor and remove it, allow any/all oil to drain if necessary. Install new filter. Fill with approx. 3.5 qt of MOTORCYCLE oil. Check for leaks and then go ride.


What is the age of Yamaha YZ125 Have serial number?

How do you move a motorcycle without keys My friends mom wants his bike out of the garage while he's off at college and he can't remember where the keys are we are only moving it a couple of blocks?

You should have a motorcyclist do it. Motorcycles are heavy! Keeping it upright is a challenge for the uninitiated - if even a mid-size motorcycle tips halfway then it's tipping all the way and it can hurt you if you try to stop it from falling. A big bike, forget it. Rather than risk dropping the bike, just have an experienced cyclist do it. A six-pack of beer should solve this problem easily. If you decide to do it without a biker's help, remember: keep it _very_ vertical and have someone flanking on either side of the bike so you never find yourself without enough leverage to keep it upright. And when it falls, remember: I told you so.

If the back wheel isn't rolling, put it in neutral. (half-a-click up from the bottom on the shift lever at the driver's left foot.) Or, pull the clutch. (left hand.)

If the steering isn't locked, I'd just roll it right down the street. Get some momentum to get up the driveway at the other end.

If the steering is locked, you've got bigger problems. You will need to put the front end on a dolly, or load the whole bike into a pickup, or something like that. Have a biker figure it out based on what you have to work with.

Plastics and Polymers

What polymers are used in bike tires?

Kevlar (Aromatic Polyamides) is used in tire reinforcement.

Polybutadiene (Butadiene Rubber, BR) is used for the carcass and side wall.

Natural rubber is a polymer, and they put polyurethane in tire rubber too. While aramids like kevlar are often used in car and motorcycle tires, nylon (less expensive and works fine) is used in bicycle tires.

WHY 110 cc ATV made in china Daymak model starter not engaging. solenoid is clicking. fully charged battery. no responce from starter?

Check to see if power is getting to the starter. If it is not check the solenoid contacts in it may be burned and not letting the power threw . If power is making it to the starter it maybe your brushes are in need of replacement or (dirt in starter ,broken magnets ,bearings or burnt wires).

Clutches and Flywheels
Harley-Davidson Motorcycles

How do you adjust the clutch on a 1999 Fatboy Harley Davidson?

First loosen the cable adjuster to give as much slack as possible (basically you're shortening the cable sheath). Then remove the derby cover (large round dome-shaped cover on the chaincase). In the center of the clutch you'll see the adjuster screw with a locknut. Loosen the locknut with an 11/16 wrench and back the adjuster screw out a couple of turns using a 7/32" Allen wrench.

Now turn the adjuster screw inward (clockwise) until it bottoms out, but not real hard. Then back the screw out 1/2 to 3/4 turn and while holding the adjuster screw in that position with the Allen wrench, tighten the locknut securely. Put the derby cover back on.

Now adjust the cable so that there's 1/16" to 1/8" (less is better) inch of play between the ferrule (that's the cable's "collar" at the lever end) and the lever bracket. To get an accurate reading, use one hand to pull the sheath away from the lever bracket while working the lever back & forth with the other hand.

Many people like to adjust their clutch cable so that the clutch engages/disengages when the lever's very close to the grip (so they don't have to reach their fingers as far), but that can cause clunky shifting and difficulty finding neutral because the clutch needs as much travel as possible for the clutch plates to fully separate (disengage). You want the very minimum of free play in the lever, in other words the lever should move only a tiny amount before the clutch starts to disengage.

The only reason you need any free play at all is so there's no undue stress on the throwout bearing (located on the right end of the clutch pushrod).

Don't adjust your clutch for comfort, adjust it for performance. At least 80% of all Harley shifting problems are caused by clutch drag from improper adjustment.

Honda Motorcycles

Why cant bikes use CNG in place of petrol?

They could but it would require a lot of modification. One might also ask, what would be the benefit from using CNG on motorbikes. The real reason for using CNG on engines is for saving fuel. As most motorbikes use far less fuel than cars, and are already more economical than cars, changing them to use CNG seems kind of purposeless. Another problem is, the CNG tanks have to fulfill far higher specifications than normal motorcycle gas tanks. This would increase the overall price of the motorbike, besides the tanks would look ugly in comparison to the normal gas tanks we have on motorcycles now.
