This model has Pursang Bultaco engine built between 1967-1981, there were thirteen models from MK-1 to MK-15 The horsepower 29H.P from the MK-1 at 45 H.P. MK-15 model. For the block size and the finned rubber pads should be a model from the MK-11. Fantastic engine that won several world championships, trial mode and speed
That's a bigger-than-stock motor in there! The 125s have a centered exhaust port, the larger Buls had the exhaust to the left.
ReplyDeleteAwesome bike.
