2011 KTM EXC Review


Few entry-level, large-displacement enduro motorcycles can compare to the KTM EXC line, which many consider to be the best in the market. While this may be debated, no one will argue over whether these bikes are worthy of being considered as the best. The EXC line comes in a small 250cc, a trail-worthy 350cc, the popular 450cc, and the slightly larger 500cc (in select markets). For most, the 450 is the model they're likely to enjoy for its balance of maneuverability on the track and capability on the street.

The 2011 KTM EXC series of enduros are well liked for their focus on offroad capability and attention to emissions requirements for California green labeling. Riders commend the larger 450 for its surprising agility, handling more like a smaller 350. KTM's design details and unusual 180 engine configuration are to credit for this, giving even the larger 450 and 500 bikes a slimline profile and lighter feel than much of the competition in this size.

The rider will immediately note the flexible performance of the 2011 KTM EXC. The factory seat is uncomfortable for many, especially on the road, but the bike handles well on the track with the added bonus that it can be ridden there legally on the street. Offroaders might appreciate the slightly better grip the squared off seats can offer. Overall, the 2011 KTM EXC is a great choice for those looking for a capable enduro.
