Q. My height is 5.3ft, is it comfortable for me - Apache 160 4V?

When you get on the bike you would find no issues. But to your legs won't touch the ground completely. It becomes tough to move back and forth. If you want to alter the seat height by changing the suspension, it would be really a bad idea. Your spine will hurt and You ride the back slightly by leaning forward ( It doesn't matter in a normal drive), so if you alter the suspension levels your stomach will hurt. Unless you are confident enough get off the bike to drag it back and forth, you will find some difficulty.

Its the same answer that i gave earlier .My height is 180 cm. Its very comfortable for me. For you I don't think it will make a great difference. It should be comfortble for you as well. In my opinion it is better to have test drive first. Though i am very confident of the ride quality for you. You will not face problem while riding it. You will love it.
