For 2008, KTM won the 85cc shootout, however there are more things to consider than someones opinion on what bike is best. Pick a bike that suits your riding style and size. Also, it doesn't matter how good a bike is, if you don't have a shop to help you with getting parts and technical knowledge, your bike is just another bike.
No I have a KTM 125 2 stroke and I have had one thing after another break on it. The service at the KTM dealer I have to go to "Evansville Super Bike" is terrible, they will never give you a straight answer and getting something fixed literally takes 5 months. BEWARE NEVER BUY A KTM!!!!!!!!!. Stick to Honda for hassle free riding.
ktm 105's are very good. they are a perfect step between a full sized bike and a mini. Although there arnt as many after market parts you can still make the bike work for your weight and height. the bike tops out at around 80mph and weighs around 150-200lbs.
the ktm 105 is way faster that a ttr
The KTM 105 is a good bike if you are transferring from a medium sized 4 stroke to your first 2 stroke. It has plenty of power. If you ride hard you might be better of going for a 125 you will be able to ride it longer.
