Dirt Bike FAQ

It sounds like your first bike, Id get a 125 just to rag about abit and get the feel, then move up to a 250 when your ready for something abit heavier and faster!

Go to BBRMOTORSPORTS.COM and get a Powroll Thrust Chamber and you will get the performance of a aftermarket exhaust without spending 300 bones. Then get a rev box. It will let your motor rev past the stock limit witch will give you more hp. That is a good hp gain for under a 100 bones.

If you want to spend a little more money you can have the flywheel lightened at BBR for a hundred bucks. This will let you motor rev like a 2-stroke and make it pick up RPM's fast. If you do alot of wide open riding, this is the thing to do. "This will take away some of your bottom end."

If you still want more than get a big bore kit. If you do go with the big bore kit thin you will need to go with 26mm carb. The stock carb was not made to handle a bigger bore than stock.
P.S.- It is better to buy a complete kit than have the stock cyl. bore. Watch e-bay for these items and do not buy a china knock-off.

Depends on what your style is me personally would get a 250 sice your pretty big and only thirteen you will grow pretty fast. a 125 was made for a 180 or lighter person so you will weigh more than that in the future probably. Also, with racing a 4 stroke is alot more work in the long run. So if you you have someone to service it or if you know how definetly go for the 4 stroke (crf250) If not cr250 or yz250.

Clean the plug and try again with the kick if the battery is dead,
if that works - you need to do some carb tuning, if not it
could be a wiring problem - make sure you are getting good spark to the plug

No! there should be a small metal plate on the neck of the frame that will have the info you need

Go bigger then a 125. for being 13 and 5'9 you can pretty much get any bike you want. your gonna grow some more so the height of a bike isn't an issue. because your age i would stay away from a 450 but maybe try like a crf250r. it has tons of power for a 250 and you won't grow out of it.

Depends if you want to trail ride get a 230 but if you want to race get a 125 2stroke.

Apparently this is possible, (i asked my bf for you!) and can be done for about £200. You need, indicators, headlights, rear lights, on-road tyres, a speedometer and a number plate bracket. Then you have to register it for a first MOT at a special MOT centre (we only no of Ruislip, but dont no where you are lol) and get it to pass!
Hope this helps

No you cannot drive. Please check the listing photo, there is no left-right indicators. Better look for street bike/scooter for easy travelling to uni. There are many 50 cc scooters available on the same site.

Go with the yamaha 125, the hondas are slow, and they dont make them any more
