Having owned a few TE510s this bike is actually a 1989 TE510 from when Cagiva were getting up to speed with manufacturing Huskys. Cagiva dumped the Swedish designed two strokes but continued to evolve the 4 stroke. Guessing it's a US import by the USD forks, spark arrestors, stacked exhaust (89 only), US headlight, and adoption of the 2 stroke air box. Dirt Bike magazine tested the 89 TE510 against ATK604s and just released Husaberg 501, it was starting to show it's age a bit by this stage...
