Ok Guys, I'm brand new just registered. Currently riding B-Senior class on a KTM 25OEXC. Road an enduro 3-weeks ago and was tied for 1st in class at lunch. Started off on my minute and fouled a freakin' plug. Time for the European crap to go. Strongly considering the WR450. I've never owned a 4-stroke and I'm concerned about the following: 1) At age 48 (I told you I'm an old guy) I'm concerned about all this power being managable. Comments? 2) How are the ergos for tall guys. I'm 6'4" and the KTM fits me like a glove with the tall seat. Tall guys out there..comments? 3) How stable is the bike? The KTM tracks straight as an arrow. 4) What is the preferred suspension shop to set up for rocks and sand for Pa & Jersey enduros. Assuming the stock stuff is crap. I guess I'm sending this out to anyone who has come off a KTM and I need to know what to expect. Also, any feedback on bikes bought from Cycle brokers in Canada? Thanks Guys!
