No difference on the Trixx. How many hours on your two 2017s? My 2017 Trixx just blew the splines apart at 22 hours. Just off warranty by two months. I took it to the dealer and they are getting BRP to cover the parts (around $1000CDN) and I have to pay for the Labour (around $500).Well that is strange... I have 2 2017 sparks haven't had an issue yet. I don't think there is any difference in the driveshaft on the TRIXX is there?
