  • 简介:在2013年4月正式上市的Z—oneS让许车迷眼前一亮并赢得了车迷的肯定。主要原因在于Z—ones是宗申一款顶级配置版的“高档”街车.整车设计和配置在宗申产品中都是最值得关注的.至少也应该是“之一”。的确.Z-ones有称得上“高档”的理由,先说发动机一联合意大利比亚乔针对西南地区研发的PY150发动机.将中低速扭力调整至最佳状态,燃烧充分、动力充沛,整体性能早已是深入人心,为山地及平原中低转速驾驶提供强大的保障。并采用了前后双制动碟系统,前方设置了双活塞卡钳.后方则配合大直径碟盘,让Z—onesS有着强悍的制动性能。悬挂系统在同类车也堪称高端,前方配置了以往在日式超跑上才能见到的倒立式前叉.后液压减震则由过去Z—one的双减震进化为可调中央式减震,其余细节也可看出Z-ones下足了成本.像是舍弃了传统的铅酸电池.
