Up for sale is a brand new Stealth performance rear sprocket in 48t gold to suit KTMs from 1991 through to 2009. The sprocket is brand new, still in the packet! Would be excellent as a spare or replacement for your KTM, or to change your gearing. Here is some information from the Stealth website:
What is the idea behind the Stealth or Tri-Metal sprockets?
Stealth (Tri-Metal) sprockets were born from a desire to create the highest quality and most technologically advanced sprockets in the world. The Stealth (Tri-Metal) is a combination of long lasting steel and lightweight aluminium that utilises the best of both materials. The idea was first developed to satisfy the requirement of drag racers, who traditionally use steel construction sprockets because aluminium sprocket teeth can not survive the high torque delivered through the chain drive system. But steel sprockets are very heavy. Supersprox engineers conceived and developed the combination of the two materials in 2000-2001. The sprockets were first used on the bikes of our World Championship sponsored riders with the likes of Husqvarna World Enduro team. These teams and riders know how this type of technology can offer them prolonged system performance and reduced power loss. Supersprox have counted 4 world titles since that time.
Why are Stealth (Tri-Metal) sprockets better than steel sprockets?
At Supersprox we care about the weight and of course, we care about the power. We also believe that sprockets made entirely from steel are too heavy. So keep the steel teeth and replace the inner section with another lighter material. We have tested several materials and in the end we came to the conclusion that aluminium offered the best strength weight ratio for the inner part of the sprocket. We use aerospace aluminium to produce the inner section of the sprocket, because of its high impact strength. The inner section is virtually indestructible. It is machined on CNC machining centres and is highly accurate, so it will run perfectly on your bike. This inner section is then coated with a 15 µm film of organic based anti corrosion material. This prevents oxidization (the cause of pitting) and helps to prevent your sprocket coming loose on the wheel hub.
Why are Stealth (Tri-Metal) sprockets better than Aluminium sprockets?
Whilst sprockets made from aluminium are light, there can be two problems that show up after some use. Firstly the tooth profile will change very quickly because of wear. The slightly worn sprocket will not engage with the chain properly and it will cause drag. The chain drag will drain power from your bike. You can loose as much as 5 BHP after only 40 minutes riding. Carbon steel teeth - last at least 3 × longer than 7075 aluminium sprocket teeth, so your drive system will last longer and run more smoothly. Add to this the Supersprox unique tooth design, which helps the chain stay in contact for longer and you have a fantastic life versus weight combination.
The sprockets are available in whatever size you like, and are available in either gold centres, or black centres. If you don't see the size and colour combo listed that you require, please message me and I'll endeavour to list it on eBay straight away. Hooray!
Usually, these sprockets can be up to $129, but on special for the Buy It Now price of $119! If you buy a new front sprocket as well, combined postage will be just $10 to anywhere in Australia.
