Looking 4 movie made in 80s ? where a guy pulls up on cycle w/ 44mag an shot a guy, flew over car trunk slomo

movie is probably about 20 years old or better the guys were on a road on the outskirts (poss. country) . Think it was a muscle car the one shot had, my friend says he thinks the cycle was a honda. Guy got off the cycle , i believe the said something then cycle man shot the other and they played it in slow motion ( guy flying over the trunk off his car). i think they recently started using slow motion when this film was made it was one of the 1st times we had seen it.
