Both of these are fairly simple to accomplish, depending upon whether you are paying attention or not, when you ride dirt bikes. Following a few themes in the heat of the instant, however, will land you safely without scares happening anywhere along the trail or in your mind.
Go with a 4 stroke dirt bike
If you have been considering moving up to a four stroke motor think about the environs and safety as a selling point. When a 2 stroke dirt bike careens up a jump it is prone to explosive bursts of power because of its fuel/oil mixing needs. A 4 stroke motor is a fair bit more sizeable and needs an oil pump to get everything lubed so the power ratios experienced are quite a bit smoother. Finally this gives the ground a bit of a breather because the nobby tires don’t throw quite as much dirt and the air takes a breather because the power spikes are more efficient when you ask for the power. From a safety point of view going with a four stroke makes the bike easier to handle as you manage the bike because your more sure that you’ll get the power you ask for and not the power that may show up unexpectedly.
