around 1/4" longer than a Sport Standard rear shock and stronger/thicker spring (not the right wording but near enough), assume it will fit the Paso 750 and maybe other models, G will correct me if I'm wrong.
Bought and fitted one to my Sport awhile ago and am well pleased with it, just bolted it in as supplied, haven't touched it since.

For this sort of money tempted to buy it just as a spare.
Cheers
