The Tomos has a major drawback im my opinion. I have worked on scooters for many years and know the tomos quite well, they are horrible. Let me explain, the tomos has a two speed transmission so unlike most scooters it has a hard time staying in the powerband. To make matters worse the two speed tranny is flawed, once it has upshifted it will not downshift again till you are nearly stopped. This major flaw makes the bike unsuited to use in hilly areas. If you are infact planning on using a scooter to save money on fuel, first consider a bike, then a four stroke scooter. I have found that a Honda aircooled 50cc is the best. They ones to look for are cubs on as they were known later passports. They can be tuned to high heaven and come in a 70cc and a 90cc for a little more go, also the motors will last longer and you won't have the on going expense of two stroke oil on top of at least 50% higher fuel consumtion. Just my two bits
P.S. I ran a conti 26" slick on the front of a scooter for awhile it worked ok, but not as well as before.
