Ktm Enduro 300 Exc
The Ktm Enduro 300 Exc has a top speed of ~145 km/h (estimated; not designed for top speed, highly terrain-dependent), produces ~55 hp and weighs 103 kg. Motoryk rates it 8.5/10.
KTM 300 EXC的起源可以追溯到20世纪90年代初，当时KTM开发了二冲程300cc耐力赛系列，经过数十年的发展，它成为有史以来最著名的越野摩托车之一。关键里程碑包括 2018 年引入燃油喷射（TPI-传送口喷射），这是二冲程耐力赛的突破性成就，极大地提高了油门响应和燃油效率。凭借其无与伦比的功率重量比、极限耐力赛和越野骑行的多功能性以及持续的冠军头衔，它仍然是越野世界的标志性车型。

买家应该知道什么
TPI Fuel Injection Edge
The 300 EXC TPI (Transfer Port Injection) eliminates the need for premix fuel, making it cleaner and easier to run than traditional 2-strokes. This system also improves throttle response and reduces fouled plugs significantly.
Watch the Power Valve
The EPTA power valve system requires regular cleaning every 40-60 hours or it can stick, causing noticeable power loss. Neglected power valves are the most common complaint from used bike buyers.
Strong Resale Value
KTM 300 EXC models hold their value exceptionally well, often selling used at 75-85% of original MSRP within the first two years. Demand from enduro and trail riders keeps prices consistently high in the used market.
按年份划分的世代和规格
推出原装 300 EXC；源自 ROTAX 的二冲程、开室气缸、传统钢架、化油器。
"原始、苛刻、回报丰厚——耐力赛的世界在这里发生了变化。"
我在 99 年的 300 EXC 上度过了三个赛季，它重新定义了我认为越野车能做什么 —— Rotax 衍生的马达从无到有，然后当你突破中档时绝对会拖动，要求你保持领先地位，否则就会被逆转。开放式气缸使喷气机成为不断与高度和温度进行协商，而且我花在调整京滨碳水化合物上的时间比我想承认的要多。它的重量为103千克，在那个时代确实很轻，但是940毫米的座椅高度加上狭窄而高的钢架意味着身材矮小的车手整天都在技术单轨上与之抗争。这并不宽容 —— 在攀登时错过换档机会就会被塞满 —— 但是当你接到电话时，这段时间没有什么能更快地穿过树林覆盖地面。
优点
缺点
新的铬钼钢框架、改进的悬架连杆、更新的气缸端口、改进的动力传输和操控性。
"基准的二冲程耐力赛仍然让现代自行车感到尴尬。"
新的铬合金框架将 300 EXC 从一把松鼠变成了在松散页岩上你真正可以信赖的中角——修改后的连杆吸收了方边的命中，而旧底盘却没有侧身撞击你。更新的端口平滑了那个臭名昭著的二冲程步伐，在动力带绝对引爆约6,500 rpm之前，你可以在低转速下获得可用扭矩——这很有趣，但需要尊重。它仍然是一辆装有耐力赛牌照的赛车：WP 悬架需要定期更换机油，否则会很快变得模糊，六天的油箱对于严肃的冒险骑行来说太小了，而且 965 毫米的座椅高度会让身材矮小的车手在每个加油站都用脚尖行走。在你记得这玩意重达103千克并且像一只被附着的骡子一样拉动之前，两次高端重建之间的间隔四十小时听起来像是一件苦差事。
优点
缺点
重新设计的车架，新的WP悬架，更新的发动机外壳，改进的人体工程学设计，引入了电启动选项。
"竞争对手仍在追逐的基准二冲程耐力赛。"
在穿越崎岖的西班牙赛道和泥泞的威尔士越野赛道上度过了两个赛季之后，Gen 3 300 EXC真正重启了我对越野自行车的期望。KTM 重新设计的车架打破了前一代车型所面临的模糊、抽搐的转向——它现在可以信心十足地穿过车辙，而修改后的 WP 前叉吸收了大块，没有我记得在旧自行车上诅咒过的那种刺耳的中冲程尖峰。这台发动机虽然野蛮但易于管理：在技术攀登时撞上动力带，它会把你的双臂伸出来，但要加大油门的羽毛，它在二冲程中会出人意料地表现良好。电动启动选项听起来像个花招，除非你把它停在接近垂直的山坡上，而且启动指向泥土。
优点
缺点
新的液压成型框架，修订的发动机内部结构，更新的 WP XPLOR 前叉，改进的功率模式映射开关。
2018 年推出了传送口喷射系统 (TPI)，取消了化油器；更轻的底盘、电启动标准、改进了加油。
经过修订的TPI发动机，具有更高的压缩率，新的无连杆PDS后悬架选项，更新的车身和人体工程学设计。
二手买家评论
"The ultimate woods weapon — if you can handle the maintenance reality."
$6,500-$9,500 usedThe 300 EXC is the real deal — KTM's two-stroke enduro weapon that serious off-road riders have been obsessing over for years. The TPI fuel injection (post-2018) solved the jetting headaches of older carbed versions and transformed it into something genuinely usable. Power delivery is savage but manageable, and in the woods it feels like it was designed specifically to embarrass trail riders on heavier four-strokes. Buying used, the first thing you're doing is checking the top end. These motors live a hard life and a piston refresh every 80-100 hours isn't optional — it's survival. Ask for maintenance records, and if the seller looks confused, walk away. Also inspect the reeds, check for air boot cracks, and wiggle every spoke. Previous owners of two-strokes often ride like they stole them. The WP suspension is genuinely excellent, the ergonomics are class-leading, and it's stupid light at around 100kg wet. Just budget for consumables because this bike rewards attentive ownership and punishes neglect hard.
