Whats up fellow hypercycles.... I'm selling a brand new set of Forged Aluminum Anodized Gold 6 spokes rims set for the Yamaha R6 from 1999-2002. Never been mounted, still have the box. Made in Japan meeting JWL standard which is equivalent to DOT approved. I bought these rims overseas in Hong Kong but never had the chance to install them. This is a great chance to upgrade your bike, wheels lighter, stronger, & better looking than stock rims. Stock front & rear rotors will bolt on directly. Will need a new sprocket, bolt pattern similar to the ZX7/ZX9. Great time to do the 520 chain conversion if you haven't already done so to save some more weight.
These rims will not crack like cast magnesium wheels, and will provide superior durability to the stock wheel. They are 25% lighter than stock. Reducing the weight on a motorcycle will always make it accelerate, corner and brake better.
Someone once told me that one of the best mods out there for your bike are the wheels. Here is some information about upgrading wheels on your bike.
Motorcycle weight can be classified in two ways; sprung or unsprung and rotating or non-rotating. _Wheel weight is both rotating and unsprung, which as you will read is the most significant weight to remove.
Sprung weight is everything that suspension holds up, unsprung weight is the wheel, sprocket, caliper, disks, axle and a percentage of the shock and swing arm. _Unsprung weight is the nemesis of the suspension in the war to maintain tire contact with the tarmac. _The less unsprung weight the more effectively the suspension and ultimately the tires can do their jobs. To explain this lets pretend you had a job in which you had to raise and lower a hammer as moving obstacles came by on some sort of moving conveyor belt. First you had a hammer with a 1 pound head. As the conveyor belt moved faster at some point it would become impossible to move quickly enough and the hammer would be hit be an obstacle. _If you used a hammer with a ½ pound head you would be able to negotiate the moving obstacles at a greater speed. _Now imagine the hammerhead is the wheel, your wrist is the suspension system and the moving conveyor with obstacles is the bumpy tarmac. This is why most cars have independent suspensions. _Reducing unsprung weight will improve the traction especially in bumpy corners.
Rotating weight on a motorcycle counts twice every time you accelerate or brake. _The reason for this is the engine must increase both the wheels’ linear velocity as well as their rotational velocity ._It is a little more complicated in reality, but each pound you remove from the wheels is equal to approximately 2 or more pounds removed from the chassis. Reducing the weight of you wheels will allow your bike to not only accelerate faster, but brake better as well. __
An additional benefit to reducing rotating weight it the reduction in gyro effect of the wheels. _The easiest way to understand this is to conduct an experiment at home. Get the front wheel off your bicycle. _Hold the axle with your hands and have a partner spin the wheel at a moderate speed. As the wheel spins pretend you are the forks and “turn” the wheel. _You now have a feel for gyroscopic forces ._Now imagine what a motorcycle wheel with much greater weight and speed goes through when you attempt to change directions quickly in a in a series of turns._
Other mechanical qualities being equal, a bike installed with lighter wheels is easier and safer to handle, offering sizable improvements in road holding and cornering, whilst enabling more precise trajectories and faster angle changes.
The most important features of a motorcycle wheel are rigidity and weight.
Rigidity is a paramount attribute, because wheels are continuously subject to torsional and lateral forces. A higher rigidity wheel affects positively the motorbike's balance by improving road holding and safety.
Weight is an equally important attribute, because the wheel is a continuously accelerating or decelerating moving mass. Reduced weight means less inertial and gyroscopic forces, so that less power will be needed to move and steer the motorbike, which in turn makes the vehicle safer and easier to ride, both on roads and on tracks.
To meet ambitious weight and rigidity standards these new motorcycle wheels have been designed for "no-compromise" performance, down to the least project detail, starting with the metal itself, the best forging grade aluminum alloy available, responding to quality standard Din UNI 6151.
Similar wheels from OZ or PVM can cost up to $2000.00, I am selling this set for $1200.00!!! Please feel free to ask me any questions. Thanks
