think about it your ty will have some power but the new gas gas 280 pro runs really well a bloke had one at cowm quarry excellent bike you would be able to do you comps and your stuff but you could just stick to your double disc echo lite which by the way is a awsome bike you would be good on a 07 gas gas i want one but i have all branded sherco clothing which cost about 130 pounds go on youtube and type in cowm quarry hillclimb in the search bar they are my vids but i really don't like the beta's they are the heaviest but for power and sound the 4rt's just rule all the other bikes 4 stroke power is awsome and trials bikes are not to race on if you want to do that get a ktm. it is also rare to see a ty in such good condition
