I have a 2017 LTX SE with 3600kms and not one issue and the same belt this machine is awsome.
I never understood why people feel the need to tune and modify these machines.
They pull so hard and I can tell you after 1600kms in Gaspe last week I never had the need to run it as fast as I could. Rode with 2 Vipers and 1 850 and 2 800 and guys who think they need the fastest machine should realize it's a waste of your time and money to try and get more power to a machine that has more than you need.
Buy it, ride it, enjoy it and save yourself the aggregation of voiding a warranty with a stupid tune and boost and bullshit.
Just my 2 cents
