Innovation comes in all sorts of shapes and sizes, so it is interesting today to see some progress made on an often overlooked item: the motorcycle chain.

BMW Motorrad is touting the first maintenance-free chain ever for a motorcycle, calling the product the BMW M Endurance chain. In reality, the product is made by Regina, with BMW claiming first rights to the product and rebranding it.

The BMW M Endurance chains is similar to other X-ring chains in that it has a permanent lubricant filling between the rollers and pins, enclosed by X-rings.

What is completely new however is  Regina’s design, in that it does not require additional external lubrication, nor does it require retensioning over time.

Zie Germans are still hard at work this winter back in zie mother country, as the final production version of the Horex VR6 is coming together. Today, the German company has announced the official performance figures of its new street bike, and the base 1,218cc six-cylinder VR motor comes with 161hp on tap and 100 lbs•ft of peak torque.

Making its peak power at 9,000 rpm, the Horex VR6 also makes most of its torque extremely low in the rev range. With 66 lbs•ft of torque at 2,000 rpm, the German roadster reaches 74 lbs•ft of torque at 3,500rpm, which fits well with the company’s hope of making the VR6 easy to ride on city streets.

Perhaps more interesting that the performance figures is the announced constant solid-graphite chain lubrication system. As the name implies, the Horex VR6 will constantly lube its chain, but instead of using oil or wax, as is traditionally used, the German motorcycle company has partnered with specialists at the Schunk Group, who have created a system that constantly coats the chain drive with a thin layer of graphite.

Less messy, and not prone to being flicked off the chain by centrifugal forces, the dry chain lubrication system is an industry first brought to market by Horex, and sounds intriguing on paper. With claims that it increases maintenance intervals over standard chain lubrication systems, this is a feature owners will be particularly interested in seeing reviews of as the VR6 hits dealer floors.
