Stock is 15/35 with a 92 link chain.
To match the stock front sprocket size (which is recommend) you need to go +3 teeth so that means an 18T front sprocket
15/35 = 2.33 ratio
18T x 2.33 = 42T rear sprocket

69 / (5/8) = 110 link chain in 530
The 5 in 530 means 5/8" between links. The 6 in 630 means 6/8" (3/4) between links
