When it comes to unleashing a motor’s power, a chain provides that essential link to the rear wheel. Tech guru Neil was on hand to tell us more…
FB: What is a chain and how does it work?
NC: Fundamentally, a chain’s there to provide that vital link between the engine and the rear wheel in the most effective way. It transmits energy through a succession of roller bearings from the front sprocket to the rear sprocket, propelling the bike in a forward motion.
FB: What different types of chains are there?
NC: There are four main types of chains; standard non O-ring, O-ring, X-ring and W-ring. The main difference between all four groups of chains is the addition of rubber, for lubrication purposes. Conventional chains require regular lubrication while O-ring, X-ring and W-ring chains contain factory packed grease, to lubricate the roller bearings.
It’s virtually impossible to access the area contained by the rubber, which can be both a good and bad thing. It means the bearings will remain protected from dirt and lubricated all the time the rubber’s integrity holds, but when it fails or the factory packed grease runs out, it will also spell the end of the chain’s life, because you’ll struggle to get lubricant in behind the rubber.
Typically, an O-ring chain saps 3-5% of the power put through it and for this reason, manufacturers developed the X-ring chain. The theory behind retaining lubricant is the same, although the point of contact from the rubber is substantially less. This lessens the resistance and improves the power put through the chain. In turn, the W-ring chain was developed to further reduce the power lost by the X-ring chain, while ensuring the chain’s lubrication.

DAN LINFOOT THE WORLD AT HIS FEET...
The racing world is full of characters who generally like to keep themselves to themselves, and I respect that. However, some of these people have a great story to tell. I'm incredibly fortunate to be friends with a few, have access to many more, and through my role with the award-winning podcast Chasin' the Racing, I get to sit down and chew the fat with some amazing individuals, so I wanted to give you lovely bunch a peep through the keyhole and an opportunity to get to know a bit more about some of these 'people of interest'.
ROSSI'S RANCH - LA 100KM DEI CAMPIONI
It's not every day you get the invite to trade paint, drifts and stories with Rossi and a bunch of world champions, but that's how life played out for the Neave twins a few weeks back.
RATING RUBBER...
We love a tyre launch, and especially ones of a sporty disposition. So when Michelin dropped us a line about not one, but two additions to their range, we didn't need our arm twisting to get stuck in and see what they're all about...
2017-2021 SUZUKI GSX-S750
Is the understated Suzuki GSX-S750 worth considering in the used market?
YAMAHA MT-09 - If you like your bikes nutty, naked and packed full of punch, you'll love the fourth-generation Yamaha MT-09.
Ten years ago, I found myself a part of the maddest, baddest, and arguably most illegal motorcycling I've ever a put my name to.
BACK TO THE FUTURE - KTM DUKE 990
It's been a while since KTM last had a 990 Duke in its range, but the name is back - and this new addition is perhaps one of its most exciting offerings ever. Here's why...
A CUT ABOVE
Four years on from the revolutionary release of the RCV-inspired Fireblade, Honda's given its flagship sportsbike a masterpiece of a makeover.
Steve Parrish
I'm fresh back from the South African Classic TT races and Christ, it's still bloody raining over here.
Christian Iddon
Well, my last column was all about just how I'm going to be the most prepared I could ever be for the season ahead.
SHOEI X-SPR PRO
I'll cut to it... when it comes to my kit, I don't mess around - especially when it comes to helmets.
