It is the most reliable bikes for a common man. My family had the first splendor model which we purchased in way back 2001. Its still going on and mileage 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 mainatance issues, no extra shelling of money.
However it has some limitations. The body of splendor is not strong enough, the bike is not stable at speed above 70kmph. However this limitation is dwarfed by the performance this bike gives.
