It is a most reliable bike for a common man. Our family has first splendor model which we purchased in way back2003. Its still going on and milage is still awesome.
Because of its reliability we purchased the hero splendor plus. It has modified looks and the engine is durable and reliable. No maintenance issue, no extra shelling of money.
However it has some limitations the body of splendor is not Strong enough. The bike is not stable at 70KMPH. However this limitation is dwarfed by its great performance.
