Factory Bike Friday: Adam Cianciarulo’s Kawasaki KX250F

Mechanic: Brett Mountain

According to factory mechanic Brett Mountain, there’s not a lot on Adam Cianciarulo’s Monster Energy Pro Circuit Kawasaki KX250F that’s stock. Most of the major components are either works items from Japan, or hand-made pieces build in the Pro Circuit build shop.

Of course, the exhaust system is Pro Circuit, and is a combination of titanium and carbon fiber. Naturally, it’s super light and well built.

As far as the suspension, Mountain says that Adam likes his forks to be pretty stiff compared to the rear suspension.

“That’s where we struggle, though, keeping the suspension balanced,” says Mountain. “To be able to keep the front stiff enough for him so it doesn’t feel like it’s diving on him coming into a corner, that’s usually his main deal.”

In the triple clamp department, Mountain says the team makes their own clamps and they have several different options. “The team is always experimenting with offset and triple clamp material,” says Mountain. “We usually narrow it down to one or two and then the riders pick which one they like. I think right now, the entire team is using the same clamp.”

Everyone is on the same engine package, as well, according to Mountain. “Some may like a different clutch adjustment, but as far as the rest of the engine, all of our guys have the same setup – same engine, same gearing,” says Mountain.

As far as brakes are concerned, Mountain says they run a different set of brake components for supercross and outdoors, since the ones used for supercross don’t have to endure the same amount of abuse as the ones used for outdoors.

“The front caliper is factory and it has smaller pads, which gives it more power,” says Mountain. “The rear brake is stock, for the most part, although we have a different piston in it, and we do a couple of little mods to them.”

The rear linkage is designed and built by Pro Circuit, and Mountain says the team did extensive testing during the off-season to find the right dimensions.

The radiators are works radiators from Japan, and they’re slightly bigger than stock and allow for a bit better cooling. They also have bigger radiators that they use for outdoors or if it rains or is really sandy.

The wheels and hubs are factory, as well, and the pegs, which are pretty cool, are built in-house.
