Yamaha made the engine for general performance; the valve angle was a relatively broad 50 degrees, which at enough time was considered to generally be perfect for significant energy manufacturing.[twenty five] Currently, lots of fashionable higher-revving engines have reduced the valve angle to twenty to twenty five degrees, making it possible for for a far more lesser and compact cylinder head and is also now thought to be perfect for significant-revving engines with large precise ability outputs.
