It was advertised as a SP4S... not sure it was a true sps then and I don't get what the hype is about on the SPS anyway. Yes this is a limited edition but it does not have much difference to an SP4. Few bits on the engine (in fact identical to the SP5), a carbon tank and no fan on the rad. No biggie...
Last year I saw a real Roche Rep for sale in France for something like EUR10,000. Now the Roche rep is a very special bike. Much rarer than an SPS and true race specifications. Before I managed to figure out how to finance it it was gone... Now somebody got a serious bargain there.
