Why We Choose The Pure-Dirt : Dirt bikes ?
The motorcycles manufactured for purely off-road use today tend toward the extreme end of the motorcycle spectrum. These are machines like the screaming race bikes leaping through the air in arenas around the country during Supercross races.
These bikes usually don’t make good beginner bikes. In fact, many of them are intended as strictly racing machines. Almost all of them have two-stroke engines, which means that you will have to mix oil into your gas before you fill your tank, which is a messy, time-consuming process. And inconvenient, should you find yourself miles from home without a can in which to mix fuel.
Adding to this inconvenience is the fact that puredirt bikes aren’t legal to ride on public roads.
Dirtbikes also feature an extremely abrupt power delivery. When the engine starts, it unleashes a whole bunch of horsepower in a most-surprising fashion. Riders inexperienced in handling these machines commonly suffer from broken bones in their hands. This is because the power catches the rider by surprise, causing the bike to flip over backward, crushing his or her hands with the handlebars. I’ve seen it happen more than once.
There are alternative bikes available for those who want to do serious off-road riding. The bikes I’m referring to are four-stroke trailbikes. Honda has long been a proponent of such motorcycles, and its XR series (not to be confused with the XR-L series—this gets confusing) offers terrific alternatives. Yamaha has also jumped on the four-stroke bandwagon with its Y2426F, Y2250F.
With four-stroke dirtbikes, you won’t have to premix fuel, plus you’ll find that they have smooth, easily-controllable power. Some even feature electric start! Unless your ultimate goal is to race, and you have some familiarity with off-road riding, these bikes may make a better choice for your first dirtbike.
Probably the biggest disadvantage of a pure-dirt motorcycle is that it’s not legal to drive on public roads (hence the term pure-dirt). This means you’ll have to transport the machine from your garage to the place you intend to ride - for example, in a pickup truck or a trailer. These bikes don’t meet the emissions or noise requirements for street legal vehicles, nor do they have the electrical equipment, like turn signals and horns, required in most states. In some states, it is possible to manipulate the legal system enough to license an off-road bike for use on public roads, but by doing so, you may be setting yourself up for future legal problems.

Dirt Bikes are machines intended for off-road use and aren’t legal to ride on public roads. Sometimes the term pure-dirt is used to distinguish a dirtbike from a dual-sport motorcycle. Dirtbike riders are sometimes referred to as dirt donks.

2016 New Dirt Bikes Line Up !
Key players employ relentless fiddling for next year’s dirt delights... Shiny new dirt bikes for 2016. Not for long.
Suzuki
There’s a host of changes to Suzuki’s RM-Z250 for 2016, based on successful alterations made to the 450 last year. These include Hole Shot Assist that alters the ignition map for the optimum start in a variety of conditions, and Kayaba’s second generation PSF2 air forks that save 1kg and give rapid suspension changes with a hand pump. There’s the 450’s kickstarter, and weight is shaved off nearly every engine component – there’s a total of 80 tweaks, giving a wider and smoother spread of power.
Honda
Honda’s 2016 CRF250R sees plenty of detail changes over last year’s model. They include: new cams; ports; valves; pistons and exhaust. There is also increased compression and revised mapping, plus longer forks for better stability. The CRF450R also gets the front-end changes, plus a new spring, linkage and damping settings for the shock.
Yamaha
Yamaha have made plenty of technical improvements to their YZ250F and YZ450F. The larger bike gets new cams with revised valve overlap, a better clutch and changes to the frame and suspension. The smaller one also gets a new crank, modified jets squirting cooling oil at the underside of the piston and smoother rev limiter intervention. The 450 also has launch control monitoring wheelspin and wheelies in first and second gear for faster, more consistent starts.
Husqvarna
All Husky’s motocross and enduro bikes get new forks with a smaller spindle, allowing shorter fork leg ‘shoes’ to increase trail. And they all get new yokes, brake discs and less slippery seats. The FE250 and 350 also have transmission updates, and the FE450 and 501 boast an improved clutch.
Fantic
Fantic Motors have a UK importer again. Their enduro and supermoto bikes use 50, 125 and 200cc Yamaha-Minarelli engines, the range-topping TZ200ER Caballero costing £5199. Enduro models are aimed at green-laners and club racers, and the supermoto bikes at road riders.
