Regular gas
no, it can take regular unleaded fuel from the pump but racing fuel is the best
There is not a timer on the dirt bike itself, you have to take it to a retailer and have them plug a machine into the computer of the dirt bike, it will display how many hours (off brands such as baja generally dont have the computer capability to read out how many hours are on the bike) for a street bike, you have to apply generally the same process
Honda, Kawasaki, and Yamaha are the top three dirt bike motorcycle manufacturers in the world of motocross. A Honda is often recommended for new riders who have decided to take up riding as a hobby.
Take a look at Ksrsport.com for Kawasaki minibikes.
The legal age in the UK (Cornwall) for riding a 50cc moped is 16, riding a 125cc is 17, however at 17 you can take your full bike license, and ride a more powerful bike but it must be restricted.
you can be any ages and you cant take it on the road because they are off road bike

For a trail rider, I would recommend a 125cc or 150cc 4 stroke for a shorter rider, or a 230cc if you are taller. If you want a two stroke, I would get an 85cc for a shorter rider. A 125cc two stroke would work for a taller rider if you have experience. These bikes are jumpy and very fast, so if you aren't experienced, take a class and only get one if you do very well. A full size 2 stroke requires good throttle control and they have more HP. For a 125cc, I would only get any year yz 125 (yamaha) or a 2001 to 2003 kx 125 (kawasaki). Other 125's aren't very good. My first and only bike is a 2001 kx 125. I've had it for a month and I love it. ONLY GET ONE IF YOU KNOW U R READY. (A 150cc four stroke is a good trail and race bike)
Just normal gasoline
you can buy a real shop repair book on your bike from bike shop or on line, the same one the bike shop uses.its not cheap but tells everthing
