Crowning Achievement


Understanding the effects of crowned roads on riding technique.

Crowned road design helps to efficiently shed water from the pavement. But it also influences the way we ride right and left curves.

Roads are engineered to disperse rainwater and minimize pooling on the road surface. The way those civil engineers achieve that is by designing roads with a crowned profile. The surface is higher in the middle (where the double – yellow is) and slopes downward to each side of the road –a bit like a pitched roof on a house. The cross slope design does much to make wet – weather riding safer. But motorcyclist should also consider how a crowned road comes into play even when the road is dry. We travel on the right side of the road here in America. On a crowned road, that means the pavement slopes from its highest point at the left side of our lane down to its lowest point on the right edge of the lane. Have you ever noticed that the left side of your bike’s tires wear more than the right? It is because your bike travels along a slanted plane for miles on end.
But here is a new slant; Think about how the crown effect comes into play when the pavement turns. In the right-hand corners, the cross slop of the road creates a banked turn within our lane, providing slightly more traction, ground clearance and more responsive steering as we lean into the curve.
Conversely, a left-hand curve has a reverse chamber as the pavement slopes away from the rider, slightly reducing traction and ground clearance and contributing to less responsive steering. This is one reason many riders find left-hand curves to be more challenging. A more conservative entry speed, combined with positioning your head and upper body toward the inside of the curve will reduce the bike’s lean angle and more than compensate for any compromise in ground clearance and traction due to the crowned road.  With a little practice, those crowned left-hand curves may become your crowning achievement!
