07-09 WR450R Vs KTM off-road
Posted January 19, 2010 - 08:22 AM
I'm sort of kidding but not really, my KTM RFS never boiled even at 12K feet on super steep climbs (had the fan installed). BUT most all the KTM's I ride with boil over quite a bit. I've never boiled my 06 WR250 or 07 YZ450 anywhere and I routinely ride steep and or tight high altitude trails 8-12K feet. Many of the KTM's that I've seen boiling over have auto clutches (owner probably rides a gear too high because they easily can) as well as air restrictive radiator guards. I would skip the cheesy auto clutch and only use radiator braces like Works Connection or Enduro Engineering with the stock louvers in place.
I would pass on all the 4 strokes discussed above and get a 2 stroke. The 250/300 KTM's are really nice (although still boil over) and my YZ250 is the best bike I've ever ridden once converted to off road. 5 minute oil changes, no valves to adjust/replace, feels like a downhill mountain bike in the tight stuff, feel fresher after long rides, the list goes on....
