(bike games aren't really my thing so I can't justify the 27euro),

that's understandable, but it might be a good time to let you know that for the 27 euro, not only do you get the full GPB, you also get a full licensed version of WRS(World Racing Series), which may very well be more up your alley.
getting 2 sims for 27 euro is a great bargain, and that's me talking from south africa, where i am up against a nasty exchange rate, as well
