Both parts are from a 2016 zforce 500 (maybe the 2017 also as I have not looked at that one). You replace the factory dipstick with the extended one and the tube. You will need to buy the extension tube, the extended dipstick, and 2 O-rings. Part numbers are as follows
Dipstick - Part# 0GRB-011001
O-Rings (you need 2) - Part# 0110-013030
Extension tube - Part# 0800-011011-1000
All these part numbers are from Alpha sports website so I hope they are CF Moto part number. I dont really buy from them anymore due to HIGH shipping cost and long delays on parts and them loosing my orders on more than one occasion but I still paid for them...but you can if you would like. Or just get them from your local dealer.
