    Yes Buls are beauties, mine is still undergoing a rebuild in two versions, bone stock with NOS parts, (this takes
    some time) and contemporary "pimped":

    After 1 1/2 years I hope to get the bike completed for spring. This rebuild in two versions, -I like both- I have underrated quite a bit :evil ...

    Thank you ... You still find this Sherpa 199b here and there, around 1700 where made.

    The blue-white colorscheme - which fit's very nice in my opinion - was designed to honor the Finnish rider Yrjö Vesterinen. He was three times in a row world champion with the Sherpa, 1976 - 1979. Expecially with this model he was third in 1981 and he also won the Scottish Six Days and the British championship.

    Technical this model was the first and last Sherpa that got a six speed gearbox and has the "biggest" engine for trials bike Bultaco developed. The engine has 340cc.

    The engine has a huge crank with around 6,5 kg, the rotor weights 3,4 kg and has too an extra flywheel on the clutch side with 2,6 kg this makes 12,5 kg of rotating masses. Therefor the engine produces extreme torque already when idling but is not very lively ... Maximum speed is btw. 87 km/h in standard gearing (55 miles/h) and the engine
    doesn't like high rpm, (max rpm is 5,500 - 6,000), and feels quite well at low speed.

    You just aim the route, then twist the throttle a little bit and the bike rolls nearly unstoppable forward, undependable to the underground or slope, it's too quite light: around 95 kg in standard trim.
