hi yes the bigger wheel makes a big difference only had my kymco a few weeks but it feels safer than my sym fiddle i donr have to grip on as much and the bumps iron out a lot, I found tyre preesures and I am just ordering some gear oil so on monday I will changr oil then gear oil and have a look at brake oil i have dot 4 ready for that,it was just serviced according to the man i got it from but for my own peace of mind I will change all the fluids and make a note of the mileage, I have used the sym just for local runs and overall its been great,quality is good engine is excellant I upgraded the battery as I put hot grips on it, but I really like the kymco it feels a lot smooter I also looked at a bigger wheel second-hand sym but the prices were hight I picked up the kymco for £645 2015 model low mileage had new tyres and he delivered so its a bargain and 12months mot and i hope to get a good few years out of it,i always get them serviced with my yearly mot and keep it garanged
