I love it, i thought i was trying by travvelling 6000km's this summer through europe on my 638, also trough your country..
i like the 634 model better but the 638 has a higher and larger seat and must be more comfy.,.
Did you ever get overheating problems?
Do yu (also) think the 634 engine is better then the 638 engine, despite the double bearings of the crankshaft of the latter?
