Ktm Sx-f 350
The Ktm Sx-f 350 has a top speed of ~175 km/h (estimated; top speed is not a primary design focus for motocross bikes), produces ~63 hp and weighs 101 kg. Motoryk rates it 8.5/10.
KTM SX-F 350于2011年推出，是与红牛KTM工厂车手塔迪·布拉祖西亚克合作开发的，其灵感来自于制造一款功率为450级但操控性为250级的自行车的愿望。当瑞安·邓吉乘坐350赢得2011年AMA 450越野摩托车锦标赛时，它很快成为标志性车型，这在精英比赛中证明了这一概念。它仍然是KTM最著名的越野摩托车赛车之一，将轻巧的灵活性与令人印象深刻的功率输出融为一体，独一无二。

买家应该知道什么
Best Power-to-Weight
The 350 SX-F punches above its class with nearly 350cc power in a 250-weight chassis, giving riders a competitive edge in both 250 and 450 classes. This makes it uniquely versatile and highly sought after on the used market.
Watch Valve Intervals
The high-revving engine requires strict valve clearance checks every 15 hours of riding — neglected maintenance is the #1 cause of expensive top-end failures on used examples. Always ask for a documented service history before buying.
Strong Resale Value
KTM SX-F 350s consistently hold strong resale value due to high demand and limited used supply, often selling for 80-90% of retail within the first year. Well-maintained examples rarely sit unsold for long.

二手买家评论
"The best motocrosser money can buy — if maintained religiously."
$5,500-$9,500 usedThe 350 SX-F is KTM's sweet spot machine — punchy enough to embarrass bigger bikes out of corners, light enough to flick through rhythm sections without wanting to die. That 350cc engine is genuinely clever engineering: rev it like a 250, get 450 grunt on exit. Used examples can be absolute gold or complete nightmares depending on maintenance history, so bring a magnet and check the frame welds carefully. These things get flogged hard. Maintenance costs are real. Valve checks every 30 hours, piston every 80-100 if it's been ridden properly. Ask for service receipts — if the seller looks blank, walk away. Worn linkage bearings and tired suspension are your biggest used-market headaches. Budget another $500-800 for a full refresh on a high-hour bike. The WP suspension is decent but not Showa-level plush straight off the truck. For the right rider though, nothing else does what this does. It's the thinking man's motocrosser — technically demanding but enormously rewarding once you're dialed in.
