I am full aware of the many applications of nikasil.. I was just taking issue with the broad statement regarding motorcycles. By the way, the BMW and Guzzi are not high volume production in comparison to the rest of the industry. Snow mobiles either, and I have repaired plenty of those as well. I would also suggest that Beemers, especially, are better maintained than a lot of vehicles. Most nikasil cylinders also run a lot lighter ring tension to decrease the wear on the bores, which if you are looking for max HP is a plus, but not neccesarily for long term usage.Once again the moto-cross boys, and they are boys now days, always carry a spare set of rings or 2 and pull the jug after every event. The owners manuals even reccomend a frequent ring change to keep top performance.As stated, I do think the block is beautiful, I would just not mind the extra weight of steel sleeves. The thickness wouldn't have to be that much because of block strength and servicability would be better IMHO. I guess I have spent to much of my life repairing others failed components and that is what I base my preference on.
