Hi, I'm currently riding a lightly modified KDX 220. Yesterday a friend of a friend let me ride his 520SX. In a word: WoW. In fact too much wow -- but it did really get me thinking of a 400xxx. I happened to find a barely used '01 400SX for sale that I'm going to go ride. I'd be interested in folks views on: price (seems the E button models are hotter selling units than the SX's, true?), any other reason I should be considering the exc or mxc models? (besides the obvious lights, etc.). I don't race, but I sometimes ride hard with my friends -- anything from tight woods to steep hills...

Thanks for any help/insight you can offer...

The only, ONLY draw back to the '01 400SX is the small tank IMO. I would love to have one as a stable mate to my 300. Maybe the perfect bike(s) for me! You don't need estart on KTMs.

Thanks! I do have another Q on gear ratios: How is the SX geared relative to the EXC and the MXC? I think I'll cross-post this in the other current thread on those models...

I hope I have this right. 1st, 2nd same, 3rd, 4th, 5th, 6th are closer ratios on the MXC. You will probably sacrifice 8-10 mph on top with the mxc vx. exc.

Hey guys, I have both the 400 and the 520sx. After riding each one at least five times, I can tell you that I still can't tell you which one is a better choice. As advertised, the 400 does not tire you out as much and the 520 has blinding top end. The 520 revs a little slower and does "handle a little heavier". I have only added one tooth to the 400 rear sprocket, two might be better. I tried a smaller counter sprocket with poor results(took away too much rev and top end) on the 400. When I get a chance to take both bikes to a track and ride them back to back,maybe I can shed some more info. If the lap times are close, I will definately keep the 400 due to the less tiring effect.

Thanks for all your help -- I test rode the '01 400 SX today and bought it on the spot. It was a sweet deal with only about 4 hrs. on the bike -- it's close to new (but a LOT less money). I'm thinking a steering dampner and possibly bigger rear/smaller front sprockets for the tight woods work. What a FUN bike!

I got to ride my 2001 Katoom 400sx today and it rocks. The gearing is way tall so i installed a 13 tooth front sprocket and that helped a bunch. I think 14-52 would be the best set-up. It helps use 2nd and 3rd more but lets your powerband be plenty broad.

Mine is bone stock except for a WER stabilizer, the gearing, and some Acerbis handguards.

Most fun bike i've ever owned.
