Great News!! We finally have the chain conversion kit available. Price to the USA is UK£498 plus shipping. To see what it looks like just enter the code XRace20757 on our products search at www.trojan-horse.co.uk Now available and exclusive to Free Spirits/Adrenalin-Moto, this chain conversion is a must for those wanting to race or do serious track days on their XB9 or 12. This kit works in conjunction with the stock swingarm so no need for expensive modifications. If needed the stock belt can just be put back on. The chain is adjusted by means of the adjustable tensioner, which sits where the stock belt tensioner would normally go. This system was used successfully on our race bike in 2003 and on the Free Spirits race bike in 2004 with no failures. It also has the advantage of maintaining a constant wheelbase regardless of sprocket size, and of keeping the wheel absolutely central in the swingarm. The chain conversion kit includes 4 rear sprockets (50-49-48-47 teeth), a chain idler (to stop the chain hitting the top of the swingarm), an adjustable chain tensioner and a 21 tooth front sprocket (no spacers needed). All parts are CNC machined and are of the highest possible quality. The chain is not included, although we can supply if required. A 520 chain with 120 links and a master link should be used (4 links need to be removed). It is fully flexible, you can use it for track days and then take off to put the bike back to stock for road riding if you wish. Parts are available individually although we are still waiting for pricing of these. Regards, Adrenalin-moto/Trojan-horse  | ||

F00kin'-A nice. Cost for the kit? I'd like to see pics of the idler that protects the swingarm installed. Sherm | ||

How about providing an endless chain, without a master link, so that it can be mounted like a belt. That way, there would be no need for any chain tool. | ||

so how would you be able to change rear sprocket size without altering the chain ??? no way to alter the wheelbase to compensate remember | ||

chain tensioner should take up/allow slack for changing sprockets. Or so it would appear. | ||

If you take a look at the chain tensioner wheel assembly you'll see that that it is made in two parts. The black part is fixed to the existing mounting studs whilst the silver piece holding the jockey wheel is able to move by means of the adjustable threaded ball joint fitment. There is enough adjustment to cover the 4 sprocket sizes supplied. On our race bike we had a choice of 10 sprocket sizes and this extra adjustment need was catered for by having 3 different size chains to cover all the sizes. What we found though was that we didn't use most of the available sizes and after 2 years of development the most useful sprocket sizes are the ones in the kit. If bigger or smaller sizes are needed then we can supply those also. The idler wheel that protects the swingarm is the smaller black piece at the foot of the picture. This just bolts to the existing fittings at the top of the removeable section of the swingarm. Fitting or removing the whole kit should take no longer than around 1 hour at most  | ||

Trojan: Real nice. 498 #'s trans to bout $1000 green backs right? | ||

It would be less than US$1000 at todays rates, but not much. It works out at approx US$945 plus shipping. Exact shipping figures depend upon destination and total package weight. This pic shows the prototype kit fitted to one of last years bikes. The Chain holder wheel can just be seen behind the footrest assembly.  |
