STAR TEK 5 Swept Spokes -Rear Wheel - 6x17" - 21017-8039-16-250

Item Summary

THE STAR TEK WHEEL

23 years of design experience, beautiful creations and bold imagination have led us to this point.  BST’s new Star TEK is a coming of age – the child of the BST original, the Diamond TEK.  With such a classic heritage of engineering with carbon fibre, how could the Star TEK be anything but stunning?  Its pedigree shows in the sleek modern style, the bold cut outs and the angled spoke ends.  BST is not just creating a new wheel – it’s using the most modern composite technology on the oldest working shape known to man to create value and unequalled performance.

This sexy new wheel epitomizes everything BST aims for – top quality, exceptional performance and outstanding safety.  While meeting the highest OEM and aftermarket standards including TÜV,  the Star TEK offset rear wheel 6.00 x 17 weighs an astonishing 2.2kg. The front wheel 3.5 x 17 weighs in at +- 2.4kg, and the conventional rear at 2.75kg (all weights exclude bearings and spacers).  The low weight ensures the best possible performance as it lowers the weight that matters most – the unsprung weight. 

We are delighted to bring this stellar performer to the motorcycle fraternity.  We already have the Star TEK in the superbike fitments, and also in a brand new offering for the maxi-scooter Yamaha X-MAX. 

About the Product

Dont Forget you will need a new sprocket with your BST wheels!

All wheels come with cush drives, valve stems and all related hardware unless otherwise stated. 

Performance
Weighing between 40 and 60 percent less than OEM wheels, BST wheels bestow sportbikes with sharper corner-carving abilities, faster acceleration, and quicker braking by weighing less than their production-bike counterparts. Lighter wheels are also easier for suspension systems to control over bumps and irregular surfaces, yielding more traction and unimpeded acceleration. Less rotating mass also equals less rider fatigue.

A lighter rear wheel is easier for the shock to control properly, which leads to superior power application and much higher trap speeds in competition and track days.

Design
Using high-tech processes pioneered in the aerospace industry, BST wheels are manufactured in a single molding operation. This technique produces a wheel that is far superior in strength and much lighter than any aluminum or magnesium wheel, and one that is light and strong enough for racing and street use.

BST wheels are a unique monococque (single unit) design with hollow spokes. The end result is wheels with unsprung weight reduced 40-60 percent compared to stock wheels. This delivers the lowest possible moment of inertia, a critical factor that affects all aspects of motorcycle performance.

Maximizing the molecular and structural properties of carbon fiber, BST has reduced spoke and rim weight without compromising their strength. Mass is therefore concentrated in the hub, reducing rotational inertia. This results in quicker acceleration and braking, allowing faster corner entry and exit speeds.

Manufacturing
BST designs the tooling, molds, wheel and hubs, then manufactures them in its state-of-the-art factory. Precision cutting machines, like those used in the aeronautical industry, ensure that the process is repeatable and meets the highest certification standards. BST uses only the finest “prepreg” carbon fiber, which is embedded in a top-secret resin matrix epoxy. Carbon-fiber layup is done in a dust-free and temperature-controlled “clean room.” The wheels are cured in a superheated steam oven, or autoclave, at 260 degrees and 85 psi. This produces the best material compaction and smoothest surface finish. Every step of this process is logged, the entire history of each wheel is stored and stamped with a unique serial number. To ensure the highest quality manufacturing processes and components, BST’s entire operation is managed under strict, new ISO 9002 standards.

About BST
Established in 1992, BST is based near Johannesburg, South Africa. BST engineers and manufactures the world's finest carbon fiber motorcycle components from wheels and frames to fuel tanks and fenders, to the highest international standards. The standard equipment wheels on Confederate and Norton motorcycles, BST was also chosen to provide wheels and produce the carbon-fiber frame on the radical MotoCyz project. On the world stage, BST wheels have been proven at every level of FIM Grand Prix roadracing competition and have won 12 national championships.
