Yrjö Vesterinen

In 1983, having relocated to the UK, Vesterinen only contested the British, Irish and Finnish rounds. He was suffering from a reoccurring back injury that meant it sometimes took weeks to recover from riding an event and he decided it was time to retire from high profile competition and start a trials based business with his wife Diane.

1982 was the year Vesterinen started slipping down the ranks as new riders started working their way to the top. He finished 10th in the World championship which was won by young Belgian Honda rider Eddy Lejeune.

Switching back to Bultaco Vesterinen was again third in 1981, taking a consolation win in Finland, and also retaining his national title.

Riding a Montesa for the 1980 season, Vesterinen again battled reigning champion Schreiber the whole season, taking a win at the German round. But it was Swede Ulf Karlson who became World Champion at season's end with Schreiber second and Vesterinen third. The Finn did make history during the 1980 season by becoming the first foreign winner of the Scottish Six-Day trial.

Although Vesterinen once again scored well during all rounds of the 1979 world championship, his podiums and win in Belgium were not quite enough to hold off determined American Bernie Schreiber who took four wins throughout the season and managed to edge out Vesterinen for the title.

1978 was a season long battle between Vesterinen and Lampkin, with Vesterinen taking the title by a mere two points after twelve rounds. He took four wins during the season to Lampkin's three.

Vesterinen retained his FIM World title in 1977, scoring in all twelve rounds and taking wins in Spain and Czechoslovakia among his six podium finishes, becoming the first multiple trials world champion.

Not wanting the same outcome for the 1976 season, Vesterinen started out the season with a win at the opening Irish round. During the season he finished 2nd to Rathmell in France, 2nd to Mick Andrews in Italy and second to Ulf Karlson in Sweden, along with wins in Germany and Finland to take the title ahead of the British pair of Rathmell and Lampkin.

1975 was the first year of the re-titled FIM World Trials Championships. Vesterinen finished second to Martin Lampkin at the third round in Spain, and by round eight when he won the Canadian round realized he was in with a chance of winning the championship. He finished second to Malcolm Rathmell at the following US round then took a welcome victory at his home Finnish round, closing in on championship leader Lampkin. A pair of wins in Switzerland and Germany closed the gap even further, but a fourth place at the final round in Czechoslovakia, with Lampkin in second handed the title to Lampkin by one point.

A best of second at the 1974 British round behind Rathmell but ahead of Andrews was to be the highlight of the season, with podiums in the US, Germany and Czechoslovakia helping him to 5th overall.

Vesterinen slipped back to 7th in the standing for 1973, standing on the podium twice, with third place in Finland again behind Rathmell and Andrews, and third in Germany behind Martin Lampkin and Rob Edwards.

A switch to the Bultaco camp during the 1972 season saw Vesterinen retain his Finnish national title and take 6th in the European championship. Scoring a good fourth place in Finland and taking his first series win in Sweden.

Returning to the European championships in 1971, Vesterinen scored points at four rounds, his best being a third place podium finish in Finland behind Malcolm Rathmell and Mick Andrews, and a second in Sweden behind local rider Benny Sellman.

During 1970 Vesterinen won the Finnish National Trials championship and contested the FIM European Championships for the first time. He finished 4th in his home Finnish round and also scored a 10th place in Sweden, ending the season in 14th place.
