49 cc too small for highway
Great bike but Kawasaki 440 (I felt a little too big on it, and with a passenger it was questionable on the highway) For a big guy like me it was still fun for back roads!
Suzuki 750 great for highway (I went camping in New Hampshire with it)
Honda Goldwing 1100cc- a real highway cruiser
My 1500 CC Honda Goldwing - a great bike
In order to be classified as a moped, it has to have a cylinder capacity
of no more than 50 cubic centimeters and an automatic transmission.
It has to be capable of a maximum speed of no more than 30 miles per hour. Naturally it has to comply with all applicable Federal Motor Vehicle Safety Standards.
You have to have a moped sticker, issued by the RMV. The sticker has to be affixed to the moped. The sticker won't be issued unless it meets the above requirements.
Moped operators are subject to the traffic laws, rules and regulations of the Commonwealth of Massachusetts.
Mopeds have the right to use all public ways in Massachusetts,
except limited access or express state highways where signs prohibiting bicycles have been posted.
Mopeds may use bicycle lanes next to various ways, but are excluded from off street recreational paths.
Moped operators must signal their intention to stop or turn by using either hand.
Mopeds may keep right when passing a motor vehicle which is in the travel lane of a way.
Mopeds will not be operated:
For More info on the federal level
sources differ but here is the essence of it all.
"Brake horsepower" (BHP) is the rating for highway use.
6 Bhp is the legal requirement for access to interstate and limited access highways.
Modern 150cc and over can usually meet this requirement.
Some old bikes may not.
But! If you are cruising along the highway on a 150cc bike at 40MPH don't be surprised if you end up having a nice conversation with the state police.
Most importantly the question would be if the motorcycle can handle
your weight when in aggressive traffic situations such as
highway speeds and lane changing, passing, etc.
Can it keep up with regular highway traffic?
I had a 2 cylinder 440 cc bike that felt too light on the highway with
my 250 lb body on, and with a passenger it was worse. The grandness of the highway made it feel as if I was on a bicycle.
I wish I still had it for backroads!
You have to be able to get out of the way of a situation with a bit of additional power, but if you are at the extent of your power, you can't speed up past a "situation".
It was nerve wracking to be so vulnerable.
My 1100cc Goldwing is much more stable as is my 750cc Suzuki.
As of 2013 the Honda Goldwing 1500 that I am using is a strong bike and has withstood a lot of travel through the USA and Canada.
I now have it hooked up with a matching colored trailer, SiriusXM satellite radio and a GPS as well as the other great things that come with the bike. It has a set of flat floor boards. This is a great Highway Bike.
Essentially, if you don't have enough power then you don't have enough control.
Can it brake well?
California Gov says:
"A motorcycle is a vehicle whose motor displaces more than 150 cubic centimeters and has a seat or saddle for the use of the rider.
It is designed to travel on not more than three wheels in contact with the ground and weighs less than 1,500 pounds."
"A motor-driven cycle is a motorcycle whose motor
displaces less than 150 cubic centimeters."
"A moped or motorized bicycle"
There are two types of motorized bicycles, defined in the California Vehicle Code.
(VC) Sections 406(a) and 406(b). Section 406(a) VC refers to a moped or motorized bicycle as any two or three wheeled device having fully operative pedals for propulsion by human power, or having no pedals
if powered solely by electrical energy, has an automatic transmission, and a motor which produces less than 2 gross brake horespower and is capable of propelling the device at a maximum speed of not more
than 30 miles per hour on level ground.
Section 406(b) VC refers to a motorized bicycle as a device that has fully operative pedals for propulsion by human power and has an electric motor that:
In China a motorcycle with a large engine can not go on the highway and mopeds and scooters are also deprived of using the highway. I saw a beautiful new Harley Davidson in Shanghai and it could't go on the highway legally. That is different from the USA, but they have rules to follow for a reason.
