Poor product service and knowledge

I purchased a big boy rs adventure 150 in December, I received it on the Friday and Saturday on my way to work broke down on the highway with only about 20km on the clock also losing a full tank of petrol, sent it back to be repaired the very next Saturday the same thing happened, this happened on 4 occasions when eventually I insisted the bike goes to big boy head office for repairs after them having the bike for about a week they eventually sorted it out, now I am 9000km in on my scooter and was told by the dealer who done my 9000km service the clutch needs to be replaced due to long distance riding, when I purchased the scooter the dealer confirmed the distance I will be traveling is not an issue for the bike and also said the clutch and belts get check at 30 000 kms nie I get told At 9000km THE CLUCH NEEDS TO BE REPLACED I also mentioned to both dealers at the 500km service and other services that there is a shudder when pulling away and they said it's nothing.
