Do they still make 2 stroke dirt bikes?
This response will address race dirt bikes and ignore the entry level air cooled 4-strokes such as the TTR's, CRFxxxF's, KLX's, etc. The 4-strokes tend to be a little better on fuel and pollute less as a rule. Gone are the days of 4-strokes lasting forever and being bullet proof. The race 2-strokes and 4-strokes enjoy a similar reliability history with the 250's being somewhat worse due to the high RPM's they run. 4-stroke power delivery is more desirable by some groups due to the low end torque and smoothness. There is still a small weight penalty (5-10 lbs in many cases) with 4-strokes. Probably universally the most undesirable aspects of the 4-stroke race dirt bikes is the fact that 1) they can be very difficult to start, 2) parts and accessories typically cost 2X to 3X as much (rebuild parts, after market exhaust, etc.) as 2-strokes. 3) the horrific costs associated with valve jobs (titanium) and the frequency some brands will require this repair. Why did the 4-strokes all but replace the 2-strokes in motocross? The AMA changed the class rules such that a rider will get the most power from 4-stroke in a given class. It is rumored that the AMA sold out to the EPA. To put it another way, the power of a 2-stroke 125 does NOT equal that of a 4-stroke 250. The power of a 2-stroke 250 does NOT equal that of a 4-stroke 450. The AMA has pretended it does in an effort to kill the 2-stroke. The 2-stroke is alive and well (and often preferred) in the freestyle MX sect as well as the off-road market (GNCC, hare scrambles, enduros, etc). These 2-stroke bikes are plentiful among the European mfr's such as KTM, Husqvarna, Gas Gas, etc.). Yamaha's YZ250 is still available as well.

Gas to oil rotio on a 1993 Kawasaki KDX 200?
The gas to oil ratio for a 1993 Kawasaki KDX 200 is typically 32:1, which means mixing 32 parts of gasoline with 1 part of 2-stroke engine oil. It is important to follow the manufacturer's recommended ratio to ensure proper engine lubrication and performance.

How does inertia apply to motocross?
There are lots of ways inertia is applied to motocross. I will start this off, add things as you think of them. First off, the definition of inertia is the resistance of an object to a change in its state of motion. (1) A heavier flywheel carries speed farther, but is also harder to slow down than a light one.

What happens when bike suspension bottoms out?
Bottoming out means that the suspension has compressed as far as it can, and usually it doesn't mean that much. Suspension parts frequently have a rubber block that the mechanics fetch up against at full compression.
But it will mean a harder landing that may either damage the bike or the rider.
