I guess it's a little too late, but here's some info.
The first Big bears were 5 spd. and 350cc. They handled bad and rode like tractors, and were very hard to shift. They got some minor upgrades in '92, but didn't help much.
In '93 the first Kodiak came out and was basicly a Big Bear with a 400cc engine, with slight improvements to ride, handling and shifting.
In '96 the Kodiak was upraded a little more, but still not much differance.
In '97 the Big Bear got similar upgrade, and a 2x4 version.
In 2000 things finally changed a little. The big bear became a 400 with a single range instead of 2, and it got a Wolverine style chassis for better ride and handling and Wolverine tranny for better shifting. But, they still rode pretty hard and were still hard to shift.
The Kodiak got a new engine that was liquid cooled.(all previous models and Big Bears are air/oil cooled) It got the auto tranny and a new chassis with good suspention, and part time 4x4( previous models were full time 4x4).
In '02 Big Bear got part time 4x4.
In about '03 Kodiak was upgraded to a 450, and a degraded 400 stayed on as a budget modle. Around this time the 400 lost low range. The 450 also got diff lock.
In '05 it got independant rear suspention.
In '07 the Big Bear got independant rear suspention and diff lock. The Kodiak became the Grizzly 450.
They haven't changed much since then. All are tough as nails. If any one finds any discrepancies, I typed this all from memory.
