I was gonna chime in on the other thread but Patman did the fatherly thing and broke things up.
Remember KTM makes Race bikes not Recreational bikes. The TTR's are not race bikes they are play bikes. Can they me raced? Yes.
KTM is way behind the power curve in the MX 80 department and Im sure they will have one in the next few years. Until then they will lose customers each year that are moving from 60's to 80's. As for them having a 80 class legal 4-stroke I dont see it happening for a while, if ever. Right now its a niche market, and better left to the mass producing Japanese mfg's. I think KTM has a full plate right now.
As a fan of KTM I just as soon see them add an 80, a 250 RFS and keep prgressing with their race bikes and leave the Rec. bikes for the inferior companies to make along with their guitars, stereo equipment generators, lawn mowers and cars.
Although I could be way off maybe its in KTM's longterm plans as part of their Dirt Bike takeover to make a killer play bike. Imagine if KTM did make a TTR125 type bike it would be kick arse and everyone would be saying what a pile the Yamaha is..........................
