Torn between the QSC kit or cv tech whole primary unit. This quad will be primarily raced as a XC quad it is a sportsman which is basically the same mechanically but there is not a lot of race talk over there. There is only about 150.00 difference between the 2…I’m not a pro racer by any means so I don’t need the new drive and driven setup, just can’t decide between these 2 units.
