GS 300 TVC - 1992
The muscle man of enduro racing
The Austrian KTM marque is one of the great names in the off-road motorcycle industry. Since the 1970s, its output and the immense number of sporting victories it has won have entered it into motocross and enduro history. But with the 300 GS TVC, the Mattighofen factory moved into a higher gear.
A New Beginning for KTM
The KTM has always been a dedicated sporting machine, improved from year to year, right up to the time that a new basic design was called for. Setting aside a certain conservatism, the factory developed an entirely new machine in 1989. This ultra-modern 250 combines the best features of the competition and is a common basis for motocross and enduro. From this compact and ergonomic machine Â– its innovative engine has a double TVC valve on the exhaust Â– a 300cc version appeared in 1990.
The GS 300 TVC supplanted the traditional 250 in the affections of many enduro riders. Within the dimensions of a compact and well-balanced 250, the stable and precise 300 offers the advantages of a larger capacity without the attendant inconveniences like noise and harshness, making it a most enjoyable enduro mount. It's just a shame that Erich Trunkenpolz (the "T" of KTM) passed away at the end of 1989, before he had a chance to witness this best KTM enduro bike in action.
