Aprilia RS250

Hi! Have my A-Schein since Feb05. I now also like to buy a motorcycle. Think of an Aprilia RS250. Sure – for the first time throttled The insurance is according to my veteran only 20-25Euro/month. But I would still have some questions. -the maximum performance comes due to the 2Tacter only at 11,000 – at 12.500 is the red area – that means nevertheless, that I can not really take advantage of the 56PS or? -Is it true that spare parts, maintenance… are extremely expensive compared to others?? how h och are the maintenance costs/1000km – can you say that?? – is a 2stroker not more prone to error than a 4stroker? -for later: what can you get out of tuning measures? but this has a negative effect on the durability or – because it is not designed for the more PS?? – do you have general tips or experiences with ner RS250? Thank you MFG Lukas
