simple, ride a stock bike, then back-to-back ride the same make/model that has upgraded suspension

I will try to be somewhat short, but we are suppose to get a foot of snow tonight so.....

When speaking of "handling" other terms commonly used are "maneuverability" and stability.

Maneuverability,Handling : describe the motorcycles ability to perform complex maneuvers and also how hard it is for the rider to perform them.

Stability: Is the motorcycles ability to maintain equilibrium to outside forces.

How do we define these aspects? Well things start to get a little varied depending on whom you talk to. But there are certain tests that are somewhat universal in nature between companies.

1) Steady Turning Test: Basically you will ride around a cone in a circle or some known mark at a steady speed. steering effort can be gauged to see how "easily" the vehicle follows the intended trajectory and what input is needed from the rider to maintain course. Measured values are steering torque and driver lean angles. Radius of curvature and speed are maintained.

2) U Turn Test: Just a the title states, This test will set up a "U' corner of known radius. Steering torque is measured to see what inputs it takes to lean a motorcycle from the vertical position. A highly maneuverable bike will take little torque to roll and also to upright. The roll accelerations can also be measured.

3) Slalom Testing:: Again as it sounds the motorcycle is put through a series of cones or marks in a slalom condition. Steering torques, roll accelerations and yaw acceleration can all be gathered to determine the bikes ability to change course quickly with minimal input.

Other tests that frequently come up are obstacle avoidance testing and additionally lane change maneuvers, again similar data is gathered for roll and yaw accelerations and torque inputs required to execute these maneuvers.

I know, Too long didn't read

This is how I have evaluated vehicle handling working as an engineer.

ohh i forgot to add that a very concise book about any of this is called,

Motorcycle Dynamics by Vittore Cossalter. This has been my "desk reference" for the last couple years.

You should try actually riding sometime.

If you can hold a beer and not spill to much I would say that waz good handling.

How can you tell if the suspension is upgraded?

Just about any bike will handle ok when everything is going to plan. It's at high speed the road goes to crap, or you stuff up a corner big time, that's how I judge handling. How the bike responses to an unplanned event when the stakes are high.

Depends on how you need the vehicle to handle. Kind of why different types of bikes have different types of geometry and such.

Lots of turns requiring quick flickability will have sportbikes - or better yet - supermoto/dual sports as good handling.

Long vast expanses of blacktop calling for great stability to maintain direction meandering to the sunset will have the relaxed geometry of a cruiser or tourer as good handling.

Personal preference makes a difference too. Some guys have a tough time dealing with a quick steering bike others don't. I personally prefer quick handling. So what I consider good handling others might see as too unstable.

Good handling is mostly perception to the individual. If it was real and car tires actually did handle good you'd see them or some version there of on sport bikes and road racers. (Had to toss that in... )

Kind of like one friend of mine says, the best touring bike - FZR750, best sportbike - FZR750, best cruiser - FZR750... I think you catch his drift, along with what bike he owned.


Reality isn't quite so forgiving. After all, we do know a motorcycle with a car tire isn't the best handling motocrosser - for sure!

A 500 lb bike that feels like a 300 lb bike.

I always liked my motard type bike for this reason. All the times I messed up a corner I was still able to make corrections and keep from crashing.

In dirt, not bucking the rider off can be important too.

Holding a line over bumps is pretty important, one of the most important traits for safety and confidence.

Lee Parks says "Controlled and plush."

...But most riders are unwilling to spend the $1,000 to $3,000 for the necessary hardware, even or even especially on bikes that cost over $10,000 to begin with. The showa rear shock on the Tiger 1050 was terrible.
