it's done, I made the first ride!
switching from a EC300 to the small motor is much more difficult than I thought.
You can not ride any more with torque, you have to turn up the rpm when you want to go fast.
After some turnes on a mx track, I had a very good feeling on the bike. The stock 48mm Zockes are much better than the 45mm ones. The complete supension is on the same level or even better than the customised 45mm Zockes with the Reiger-Suspension Shock. This is the first stock suspension I've ever rode without and modifications and it works!!!
About the motor I don't whant to say too much, because I am still trying to get used to it. It is very powerfull with torque from the bottom.
I am not sure, but I think I was as fast on the track than with my EC300. Give me some weeks to get used to it and I will be faster with the EC144 than with the EC300.
I would never belive that the handling is so easy and the corner speed could be so high. Riding a smaller bike is so much more fun!!
