just like to say thanks to all the people on here who take the time to write reviews and what to do when u buy a new bike ect after looking on this site i went out and got a DHZ 160 and knew what to do to set the bike up (lock tight, grease ect) and what to change straight away(chain, leavers ect). Looking foward to taking the bike for its first ride next week and thanks to everyone who took there time explaining things on this site hopefully will be a problem free
