Data and images come from a thread on RTP, was published there yesterday. Soon the Wok engines will also be available as 4 valves, which of course significantly improves the power output, see comparison of the performance data: Known 2 valve motor: Max power (kw/rpm): 2.2/7500 Max torque (N.m/rpm): 2.7/6500 New 4 valve motor: Max power (kw/rpm): 3.3/6500 Max torque (N.m/rpm): 5.0/6000 This engine is probably the first engine to be installed in the Baotian BT49-QT20B uch with disc brake rear and 13″ wheelsImage The much more interesting thing, however, is that in the near future there are probably conversion sets for the previous engines, i.e. other cylinder head, camshaft, tilt lever block etc., for the 125/150cc engines these are probably already on the market.Image The Chinese are not sleeping at all, I am already looking forward to first reviews.
