I’m running an 18/52 set-up. I purchased a 120-link x-ring chain and cut 4 or 5 links from that. With. 17/47 you may get away with a 114 link chain. You’ll have to take some measurements to be sure, or just get a 120 and cut as required.

Hello i am new to this forum and I have a question i have a 47 tooth rear sprocket from a rollin chasis i purchased and i cannot for the life of me find a front sprocket for this bike every other frickin suzuki but not the s40 please can some one put me in the right direction thank you

The reason you can't find the stock parts, is the bike comes with a belt drive, not a chain. If it has a chain it's a non-stock or custom conversion. Nothing ''wrong'' with that, just personel prefernce. The above link should give you the low-down.
