Motorcycle Safety

No, it's illegal even though New Yorkers do it.

A helmet protects you during a fall by absorbing and distributing the impact forces across its structure, reducing the energy transferred to your skull and brain. The outer shell is designed to resist penetration, while the inner foam padding cushions the blow and helps prevent concussions and other head injuries. By creating a barrier between your head and the ground or objects, helmets significantly lower the risk of severe injury in accidents.

Absolutely it is very important for motorcycle riders to wear a helmet. It is also very illegal in most state for a motorcyclist to drive without a helmet, it is for the saftey of the driver.

Shifting up or down is directly related to the rpm. of the motor. It will vary with the motorcycle motor size.

In 2009, in the US, there were 4,462 motorcyclist fatalities.

Check your state laws. Some require the child to be 16 and have a license before operating a dirt bike. Personally, I wouldn't let my child drive on anything less than 4 wheels. I have seen 2 gruesome accidents involving underage people without experience driving a 3-wheeler and a dirt bike. I have watched my nephew on one and to be honest nothing is truly safe for that age group, but dirt bikes have a lot of tread on the tires and are made for ware and tare. As long as they watch where they are going than everything should be fine. Make sure they wear a helmet, of course you probubly know that, but in some states it is the law. And start with less power and gradually get bigger and better, they can adjust slowly without feeling they are invinceble. you might want to get the special pants and long sleeve shirt, they will protect in the event they were to fall. Look for them in the dirt bike magazines or even at a sporting store.

There are 5280 feet in one mile. Therefore, 35 miles per hour is equal to 35 x 5280 = 184800 feet per hour.

There are 3600 seconds in one hour. Therefore, 184800 feet per hour is equal to 184800/3600 = 51.3 recurring (that is, 51.3333...) feet per second.

200 Feet per second would be roughly 136.88 Miles per hour.

This is a poorly phrased question, but we'll assume you want to know a bikes top speed with a 250cc engine. First, there are many other factors that determine an engine's peak hp other than it's displacement. Top speeds are generally influenced by aerodynamics, gearing, grip, and force (HP). A rider can reduce air resistance by leaning forward on the bike. Weight will effect acceleration, not top speed.

There are different 250cc motorcycles, CC = cubic centimeters, this is the capacity of the cylinders in the engine. There is no specific speed of a 250cc bike. you could have a 250cc dirt bike that goes about 60mph, or a 250cc Honda rebel that does 80. Hope this helps a little.

As a genaral rule cruisers aren't about "top speeds" but "Max. Tourque", Kawi. and other manufacturers don't usually give "top speeds" in their literature...mainly due to legality issues. There are plenty of exceptions to the rule however. (think zx-10-14 etc.) A multitude of variables aside, rider's weight etc. With a displacement of 903cc (55.10 cubic inches) and maximum torque: 60.5 - 60.8lb.-ft. @ 3,500 rpm, a compression ratio of 9.5:1 and with a dry weight around 249.0 kg (549.0 pounds) a realistic top speed would probably be around 100 mph or 160.93 kph. You'll no doubt have a higher rpm and associated engine vibrations and a rather uncomfortable riding experience should you sustain that level of speed, however.

60-75 mph

The best way is to stand both of them on their rear wheels. Answer: I normally see them standing on their real wheels with the back second quad piggy backing on the first quad. Put something on top of the first quad to limit scratching. Also make sure you secure both bikes to limit excess movement.

I have a 2001 sporster. I usually shift at or alittle above 3000 rpm. Any thing lower puts my rpm at or under 2000 in the next higher gear, which makes my engine labor. I use my tac to shift and have never noticed the mph.

Most likely a bent shift fork.

Yes it is a physical possibility and some 14 year olds do it with skill and finesse, perhaps even a degree of competence that amazes. Operating on a public roadway is however not legal.
