I hope anyone can tell me how a powerband on a bike works. I've got KLR 600 and a KDX 200. I know what the effect of the powerband is but have got no idea how it works and no one in the KDX group seems to know the answer...so, I thought I'd give the guys at my KLR Group a go...

Powerband, think of a graph plotting RPM on one axis and power developed on the other. Different bikes have different reasons for their powerbands, the KDX has a relatively flat powerband for a small dirtbike, meaning there is a relatively even or smooth delivery of power regardless of the motor rpm. The KLR is similar. I had a 500cc Suzuki roadracer that had no power until 6500 rpm and then it came on as if someone had lit a stick of dynamite. Your KDX would be a handlefull to ride in the woods if the power curve was like that. --- duncanc@... wrote:

Forgive me if I'm being to basic here, but you probably want to define powerband, then get into how it works, or what it does. Powerband is simply a term that describes when the engine is running at a rpm range that produces usable power. So when most bikes idle, they are not in their powerband, give it a little gas, and you start getting into the "powerband". What gear you are in will also affect when the bike "feels" like it is getting into the powerband, and of course you can graph the power characteristics of an engine by plotting torque and horsepower over a rev range, but I'll leave that discussion to the Kevin Cameron types amongst us. Some bikes produce nice usable power sooner in the rev range, some in the middle, and some way up top, and some seem to do it in all spots. So, powerband itself doesn't do anything, it just describes the power characteristics of the engine. Does the power come on sudden: a thing powerband Does it have power at all rev ranges: a flat powerband You get the idea. Hope that helps a little, Ed PowerlessOverMotorcycles, WA

After moving it's time to rearrange the fleet. So the most likely bike to go is my A-15' Bought : 4/24/01 Mileage: 1025 Accessories: Moose bash plate, Tank panniers ( rider warehouse standard size) Dual Star headlight guard, centerstand, shim kit ( Arrowhead) Engine was broke in according to specs. and the 500 mile service was actually done ( with valve adjustment) by the dealer. Side covers have some surface scratches otherwise the bike is in perfect condition. Located in So. Cal. Asking $4200./Best Bgrdshark@... [Non-text portions of this message have been removed]

A "powerband" isn't something that actually "works", it's not like a mechanical piece or anything. A powerband is a range of RPM in which an engine makes the most hp/torque. Think of it as a graph. The graph starts out very small at first with low rpm's, and gets higher with more rpm's. The "powerband" is where the graph is at or near it's maximum peak. Say for example, your powerband might be between 3500 and 7000 rpm. The KLR's power really drops off after about 7000 rpm. Ryan Phoenix
