This is the category in which Technic
has been the most prolific. So what exactly is a dune
buggy? There is really no firm definition, but the general idea
is a pure off road vehicle which would not be used on the road.
They typically have a small engine, suspension, and a roll bar.
ATVs have also been included in this category due to their similar
utility.
Most of these buggies are pretty simple, but there are a couple with
adjustable frame height which are fairly complicated. Several
have suspension. Most, but not all, feature steering.
My favorite
is
8428 because of the suspension
adjustability and the excellent
wheels. The
8284 dune buggy is actually
an alternate model but was marketed as the primary model in the USA so
is included here for completeness.
