The Sammy Miller Museum is an historically important collection of road and competition motorcycles which focuses on the golden age of the sport in the 1950s and 60s. The collection includes some of the most outstanding machines ever raced, and almost all are in running order. Many have been lovingly restored, and some have been left with their original patina.

1969 Jawa Type 673 350 V-4

After competing for many years in the 350cc class with 4-stroke designs (which finished the '61 & '62 seasons in 2nd place) a very different bike was debuted at Assen in 1967. The rotary valve V-4 2-stroke didn't finish and wasn't seen again for over 12 months, by which stage reliability had improved enough to claim 3rd, 4th & 6th place finishes.

For the '69 season Bill Ivy was signed as lead rider and his first four races resulted in two DNFs and two 2nd places behind Agostini on the MV. Tragically Ivy was killed during practice for the fifth race of the season at Sachsenring after the motor seized due the break up of a conrod bearing cage. The bikes (only three were constructed) continued to be campaigned until the end of the 1970 season.

Claimed power 72hp at 13,000rpm. Dry weight 138kg.
