Your 2006 is appreciably more "ventilated" than later models. Cannot think why Suzuki would change that, but they did!This belt in running enclosed and gets pinched by variator - that would be heating up pretty good, so air has to flow thru for max longevity.
Don't think they did....What "somebody" said was...Somebody here was saying,... the Burgman has the longest Factory belt interval at 14,500 miles
And I had a Majesty too (A 250cc). IT required a CVT rebuild at less than 10K and 2 years old, tho' that came under warranty.Despite all "our" moaning, our Burgmans (400s) seem to have one of the longer belt service lives (14500 miles+) among mid range scooters - with the "as designed" engineering.
