Need some advice on KTM thumpers, need some cool-aid drinkers to chime in with some info. Looking for a 525/530 or possibly 450 in either EXC or XCW trim, primarily for mixed mountain / desert enduro riding in Utah and Wyoming. 190lb, 5'11" rider. Any suggestions as to what years are best or are to be avoided? Better to put a street legal kit on an XCW or just pickup an exc? What are the pros / cons of each? Major power or reliability difference between 450-525-530? Looking for the best combination for under $5k on the used market.
