Not sure why your 13 wasn't snappier, lighter, faster than your 12 but I had both at same time, wasn't even close. 13 was much faster and alot easier to move than a my 12.
Electronic system on 13 was much snappier as well, mapping was very different between the two.
As far as technology, has either of the other two companies tried the technologies there been using in automotive industries for years?
Some have worked great others have needed tweaking along the way but the other two companies haven't even tried to use that technology.
If companies don't keep pushing the envelope we'd still be riding steel bulkheads, trailing arms, chain cases, low chassis, high handle bars, tall seats, wide bodywork, big wide front ends, triple cylinder bogs, standard bulb headlights, plastic air boxes, aluminum overstructures, steel a arms flexible chassis, now we have less and less rivets used to loosen up, raised chassis/running boards and bulkhead and spindles, very stiff chassis, cast and glued bulkheads, carbon fiber parts, more and more parts made with aluminum that Used to be steel.
Doo n poo have gone 2 different directions
1 push the envelope with new designs based on a new and still a rigid chassis
1 keep the old chassis and bolts on a few new parts every couple years and call it a new sled also have flexy chassis and a flexy suspension.
