[QUOTE="Rich Rohrich, post: 1102330, member: 16241"] I know you are aware that has nothing to do with it being a single or dual cam design, it's a function of material costs and performance/design decisions. It's something every company has to contend with if they want to make competitive power and still sell at a competitive price. High rpm four-stroke singles that make 140 + horsepower per liter will be by their very nature maintenance intensive when compared to engines that made half that power at 70% of the rpm. Simple math really. Maintenance will always be proportional to how fast you spin an engine, and more importantly how fast you need to accelerate the valves to make it breath. If customers expect higher specific outputs and more usuable power spreads each year while at the same time demanding that the price increases be kept to a minimum something has to give and in this case it's the service life of some critical components due to material issues. The same thing has happened to two-strokes over the years, but the power levels have remained consistent long enough for some people to have forgotten how long pistons, rings and cranks used to last. Kettering said it best, "the price of progress is TROUBLE" :) Introduce a direct injection two-stroke MX bike with it's associated costs and teething issues and people will be lining up to bitch about that soon enough. ;) [/QUOTE]
