You will receive the brand new set that is pictured. This is the correct set for your electric start T160 / I have road tested this set for over 9000 miles and I have seen no wear or stretching of the primary chains. I have ridden the bike with this set across country, fully loaded for a one month camping trip, and I have ridden this bike trough the canyons hot and heavy ringing out the throttle like laundry, passing every auto and motorcycle that comes in my view. I have good shift response, and I have a clean primary which is not showing any unusual wear.
The nice thing about this kit, is that the two chains that are includes are very easily available.
