Yamaha Rd 350
The Yamaha Rd 350 has a top speed of 161 km/h, produces 39 hp and weighs 166 kg. Motoryk rates it 8/10.
雅马哈 RD350 于 1973 年推出，是 DS7/R3 系列的继任者，它配备了革命性的簧片气门感应二冲程并联双发动机，可为其排量提供卓越的动力。它很快赢得了1970年代操控性最好、最令人兴奋的轻型摩托车之一的声誉，在俱乐部比赛中占据主导地位，成为了发烧友的经典之作。尽管 RD350B 变体在 1975-1976 年问世，但大多数市场的生产一直持续到 1975 年，而且该车型留下了影响雅马哈数十年来二冲程阵容的持久遗产。

买家应该知道什么
Powervalve-Free Two-Stroke
The RD350 uses a simple reed valve induction system without powervalves, making it mechanically straightforward to maintain. However, the two-stroke engine requires regular top-end rebuilds every 5,000–8,000 miles to stay healthy.
Watch the Expansion Chambers
The tuned exhaust expansion chambers are critical to performance and are expensive to replace if rusted or dented. Always inspect them closely — dents or holes cause noticeable power loss and are a strong bargaining point.
Strong Collector Resale Value
Clean, original RD350s have steadily appreciated in value, with well-maintained examples selling for $4,000–$8,000+. Its legendary status as a 'pocket rocketship' of the 1970s keeps demand high among enthusiasts.
按年份划分的世代和规格
以 RD350 的形式推出，簧片气门感应、扭矩感应系统、双缸二冲程、347cc 发动机。
"二冲程改写了小型自行车的功能。"
1972 年，没有什么能让你为那次簧片气门的感应冲击做好准备 —— 低于 6,000 rpm 的转速已经足够礼貌了，然后扭矩感应系统启动了，突然之间你抓住了而不是转向。我已经拥有了其中的两个，但每次的能量传输还是让我感到惊讶。底盘很轻而且可以闪烁，但是当你以极快的速度行驶时，前鼓式制动器确实很可怕，而那些早期的Autolube二冲程机油泵需要持续关注，否则你将重建活塞。化油器同步是每周的宗教，而不是建议。
优点
缺点
细微的改进，更新的图形，改进的化油器，对自行车零件和仪表略有修改。
"金钱能买到的最锋利的二冲程双胞胎。"
A/B 更新足够微妙，你可能会错过并排的更新，但是重新校准的 Mikuni 碳水化合物确实清理了困扰第一代的 4,500 rpm 左右的平坦位置——达到了 6,000，它仍然会抓住你的手腕，就像你等了这么久一样。在光滑的柏油路面上，操控非常紧凑，可以与人交流，但经过改进的前叉在长时间内仍能将所有焦油条直接传送到您的手掌中。二冲程维护是一项真正的承诺：预混纪律、动力阀检查和塞子结垢仅在周二进行。让我回想起的是，1974年以这个价位建造的任何东西都不能提供这种原始的、机械的诚实感——它奖励技能，惩罚懒惰，这正是摩托车运动应该有的样子。
优点
缺点
修订了排气系统，更新了造型，改进了前叉，对发动机进行了细微调整以符合排放标准。
"虽然还是个尖叫，但是发射调谐使边缘变得僵硬了。"
RD350C 可以像有人拨动开关一样达到那个 6,500 rpm 的功率带，它仍然是你花钱在两个轮子上能做的最令人内心满意的事情之一。雅马哈改版的排气系统在怠速时听起来比较刻薄，但排放要求的失调是真实的——背靠背使用 74 年的 RD350，你会感觉高端可能缺少 3-4 马力，考虑到这台发动机已经接近极限了，这让人感到刺痛。更新的前叉确实提高了对快速弯道的信心；最初的设置模糊不清，可能会让你在横扫中途大吃一惊，而这一代人解决了这个问题。注油的可靠性仍然是让我彻夜难眠的一件事——忽略它，你正在路边重建一座没收的高端设备，不值得你陪伴。
优点
缺点
雅马哈动力阀系统推出，单冲击后悬架，液体冷却，大幅提高了功率输出。
"最后一个可以合法上街的二冲程尖叫者。"
YPVS 改变了一切——低于 6,500 rpm 的转速它是一辆可操控的通勤车，然后动力阀打开，它会像咬它一样向前猛冲。我已经拥有了三台 RD，而这一代是权威的：monoschock 后置通过快速扫地机将底盘从折衷的折衷方案转变为真正能激发信心的车型。液体冷却意味着你实际上可以在不占用活塞的情况下坐在交通中，而气冷变体经常会因为活塞而受到惩罚。诚实的缺点是，YPVS伺服电机——当它发生故障时，你的马力将降至30多马力，而且诊断出钱包空如也。
优点
缺点
更新的整流罩和车身，完善的YPVS系统，改进的制动，主要在印度和巴西市场销售。
"二冲程雷鸣仍然让现代中量级选手感到尴尬。"
我驾驶一辆 RD350F2 在浦那的交通和周末的山地跑中跑了三年，没有什么能让你为那个以 6,500 rpm 的转速开启的 YPVS 强力带做好准备——就像自行车吞下手榴弹一样。精致的整流罩实际上可以使风速控制在 130 km/h 以下，这是对前几代产品的真正改进，更新的前盘设置让我更有信心在狭窄的弯道中用力刹车。话虽如此，二冲程税是真实存在的：油箱焦虑，如果你把它拖到欢乐区之下就会弄脏塞子，以及会让卡车司机畏缩的燃油经济性。印度市场的零部件供应使其适宜居住，但这辆自行车需要机械上的同情，也需要车手愿意按照自己的条件与之相遇。

二手买家评论
"A thrilling classic, but only buy one already sorted."
$2,500-$6,500 usedThe RD350 is genuinely one of the most rewarding two-strokes you can throw a leg over, but buying one used is a minefield if you don't know what you're looking at. These engines breathe through reeds and expansion chambers, and the previous owner either understood that or absolutely didn't — there's rarely a middle ground. Check the power valves, smell the exhaust for rich running, and walk away from anything that's been sitting more than a year without a carb rebuild. The good news is parts availability has improved dramatically through the vintage community. When it's right, the 350 pulls hard from 6,000rpm and screams to nine with a mechanical intensity modern bikes simply can't replicate. Handling is surprisingly capable for a 1970s machine — light, flickable, and communicative. Just budget realistically: a proper restoration runs $1,500-2,500 in labour and parts on top of purchase price. Find one with documented work rather than optimistic promises.
