Are 2 strokes high maintenance?
While two-stroke engines run more simplistically, their need for maintenance is usually much higher. However, two-stroke parts are notoriously cheaper than four-stroke. … Two-strokes also require more frequent shifting, but riders can get a faster top speed with more power.
