@tintin,

It's difficult explaining musical terms without using more musical terms, but in a nutshell: syncopation is when a beat that is not normally accented becomes accented. For example, in a 4-beat pattern the rhythm would normally sound like "ONE-two-three-four, ONE-two-three-four," with the accent on the first beat. If you place the accents on other beats, such as "one-TWO-three-four, one-TWO-three-four," then that's syncopation.
"Motor rhythms," on the other hand, is a term given to rapid, repetitive rhythmic patterns that are fairly regular with little or no syncopation. In a "motor rhythm" (a term that many Baroque musicians despise, incidentally), patterns like "ONE-two-three-four, ONE-two-three-four" tend to dominate.
In other words, "motor rhythms" and "syncopated phrasing" are opposites. Your sentence is trying to say that contemporary violinists are very versatile because they are able to play many different styles, from the rhythmic regularity of Vivaldi's motor rhythms to the rhythmic irregularity of Shostakovich's syncopated phrasing.
