awesome bikes ! i liked the belt system on that so much , i fashioned one on to my vz 800 marauder. all in all wish i had done it sooner. smooth , quiet , no maintenance but for tension and alignment tweek every 6 to 8 k. this has a diffetent belt as the s40 belt was too short but both pulleys are s 40 original equip. 5500 miles on this experiment and no problems ! love it ! i bought this marauder brand new in 1997 and have replaced , listened to , cleaned up after 7 sets of chains and sprockets . ugh! i don't miss them at all. it was a bit of metal fab work but well worth it. ill post a video soon about it and my vs 800 vulcan from 1995! both good all around stomping bikes. now the vulcan needs a belt. that's much easier as i can get bolt on stuff for it but the suzuki was all make it yourself or forget it. it came out great .it now needs some other things repaired as it's 23 yrz old . all in the video . look up " belt drive marauder" on you tube in about a month. good video my friend . this should be helpful for anyone needing advice on these S 40s . durable little monsters . keep the shiny side up!

My 2019 Suzuki Boulevard S40 has the axle nut on the left side of the axle. Otherwise the procedure is the same. Be sure to keep that belt clean. I clean out the grooves with a small stiff brush. Keeps the belt quiet. 🙉

What is the size of the belt

Hello. How many miles or km can I ride on this bike before changing the belt, please ? Thank you.

I adjusted mine per Suzuki’s spec and had annoying belt noise. I followed suggestions on a forum for a much looser adjustment and no more noise. They unilaterally recommend throwing the Suzuki gauge away.
