I've never riden a 380, but I love my 360exc- all the power you'll ever need. Mine is trail ridden on single track, hill-climbs, woods, desert--anywhere I want to go. A very tractor like bottom end, a strong mid hit, and the top feels like a 250! I've added the FMF Fatty pipe with a Turbine core spark arrestor and a Boyesen Rad valve (reed cage w/carbon fiber reeds), and these mods increased the bottom end response.
My exc came with wide ratio tranny, 3.2 Gallon gas tank, 18" rear wheel, heavier fly-wheel weight- just to name a few of the things that make the exc's trail-worthy. If you like horsepower in a light, well handling package, this is the bike for you.:D
