CW EVALUATION
Measuring up couldn't be easier
IN OUR PERFORMANCE-ORIENTED WORLD, hard numbers are king. And while you could buy a $3000 radar gun or a $10,000 GPS-based testing system, that kind of expenditure is a bit ridiculous. Doesn’t anyone make something similar that costs less than, say, 300 bucks?
Canada’s Nonlinear Engineering took up the challenge and offers the Veypor Performance Analyzer. Compact and lightweight, it measures and calculates all of the following: quarter-mile time and trap speed, 0-60 mph time and distance, braking time and distance, and the time it takes the bike to accelerate between two user-selected speeds (what CW calls roll-ons). This multi-faceted device also has a gear-position indicator and calculates horsepower and torque.
All this is accomplished via three built-in accelerometers, which calculate the rate of change between engine rpm and wheel speed (you must first input tire circumference) to determine the aforementioned values. Multiple runs can be stored while testing and later referenced, or even downloaded into a computer for further analysis. While the graphing functions are adequate, toggling through the rather complicated menu with just two buttons leaves something to be desired.
Installation is simple, requiring only three connections (two power lines and an ignition pickup), routing of the main wiring harness and mounting the wheelspeed sensor. Beyond that, all you need to do is affix a magnet to the rear sprocket, and find space on your handlebars or triple-clamp for the unit and its mount. We tried the Veypor on several motorcycles and had no problems with any of the installations.
A couple of tips: Make sure the positive lead goes to an ignition-switched source. On a Honda CBR600RR, for example, we drew power from the headlight fuse. Also, make sure the wheel magnet is securely affixed. The supplied adhesive wasn’t strong enough to hold the magnet to the rear sprocket, so we supplemented it with RTV silicone.
Accuracy depends on the user. For example, to calculate power, you must enter the weight of both the motorcycle and the rider. If you enter the weight of the bike with a full gas tank, but test with a nearly empty tank, your results will vary greatly. Also, our test unit was consistently 8-10 percent off that of our Stalker radar gun. Still, that’s pretty good for a tenth of the price. □
