This story will you how the engines compare. what the are like, how brakes react and the in steering, handling and suspension. It give you setup tips, you how horsepower and torque differ and you which is our pick for the best four-… motocrosser for 2002.

introduce you to our testing staff and let you a decision as to their qualifications as We prefer to think that we are for all of our actions and strongly feel is a better means of passing information than pretending we are one know-it-all entity. Hopefully you have also seen test on television.

We devoted an entire show of on Speed-vision to this story and how machines compare to their two-… brethren.

As you will there are only four in this test and ATK. Gas Gas, Husaberg, husqvarna. and VOR are not included. This was completely

We wanted an extremely focused of the most popular and most motocrossers on the market so you could a well-informed buying decision.

The used for this comparison Lake Elsinore.

Perris and each prepped differently so we get an idea of how the bikes varied different circumstances. Lake was dry and hardpack on the day we tested with the present and its smooth surface was to tell us a lot about steering, and throttle control. One rider It’s a good thing riding four-strokes, otherwise the wouldn’t be that much

In contrast, Perris featured loam, deep ruts, braking bumps and epic This was the roughest course our four-… shootout, and it provided a lot of about suspension, handling and braking.

The best track to horsepower came in the deep of LACR. Although the course was glass-smooth, it taught us a lot about output, torque, gear shifting and clutch action. It helped some riders opinions on high-speed stability, and ergos. But the shootout was by no means to just three days the manufacturers.

We also went out on our own to see if the would change, and they did

For this test we selected six representing a wide range of levels, riding styles and types.

KTM 520 6X

Rider height varied 5’8 to 6’l, and rider was in the 160- to 200-pound range. All of our fit within parameters established by the as being considered normal for engine and suspension category. this test we also the manufacturers to change tires track to track yet Honda its standard Dunlop K490/K695 and Yamaha used its stock K739s at all three tracks.

KTM swapped between the Bridgestone and Michelin Starcross combos. We feel it would be an accurate if we forced the manufacturers to use the exact model that came with each bike.

We allowed them to make to create the best representation of These included fork height, spring rates, clickers, shock sag, oil level and gearing. These are all listed in our setup charts, and the other modification to note was some riders asked to use CR125R bar mounts which the bar 3mm farther forward. This is a Honda part and costs $100.

We allowed this because we the stock bar for a Renthal cashier or our riders to jump from to bike and feel at home quicker. We also insisted each manufacturer use 91-octane fuel to ensure everything was on a playing field.


125 and 250cc two-… motocross all of the bikes in this test radically different power

KTM’s 400 SX is the mellowest of the group and have what we deemed competitive with Nil IA the other Although it is extremely fun and would an excellent playbike. it just on the same level as the other in this horse-powery dominated Our crew found that it vas difficult to … jumps at the exit of turns and it is consistently in drag race scenarios.

Although it has a torquey and tractable it just didn’t build rpm as or as long as the other. And when it vibrated a lot. Hence was the least favorite of the machines.

In contrast, the extra 120cc of the KTM 520 SX a remarkable difference. The 520 is the indisputable when it Comes to sheer and pulling Power, It’s strong. hut it also vibrates a lot peak rpm and that hurt its ranking among our test We also played around gearing on tighter tracks We one tooth to the rear sprocket to the machine to pull harder out of low-speed ruts in second

Riders also found they shifted the 520 less per lap as compared to other bikes, and loved the smooth power and the solid midrange punch. The turned out to be its weak point and why it lower than bikes less power. Still, is very, very competitive in trim and both KTMs the easiest starting of the hunch.

A lot of our riders were split the Honda and Yamaha for the win in this The Honda has excellent Off-idle smooth delivery and healthy power up top, This is an all-around package and everyone the CRF was exceptionally fun to ride.
