As the others have said there are a few come from CTRs to the Zed, but what are the running costs of the CTR for those of us that dont know it? We can then tell you if its on par.
I get relatively high MPG for people on here, and on avereage see 28MPG, but thats because I do a lot of m-way driving. I think the MPG you quote is quite similar to the Zed, because unlike the CTR, you dont need to rag it everywhere to get some power
