The Dutch are surely cookin'! Here's a prototype 40mm cylinder that Jouke Rottiné from Solexnoord has crafted.

What's new? It's a nikasil cylinder, meaning that the inner coating is super durable, whilst the rest of the cylinder - which is made of alloy - should allow for notable better cooling than the stock cast iron cylinder.
Price, availability and release date is still kept a secret - or at least kept in Dutch. However, the design sounds promising indeed, and if the prices are reasonable Giant Centipedes might even consider placing an order.
