Obviously a little bored today and began to wonder, in the absence of a replacement for the ST4S, what engine might fit easily into said chassis. I appreciate that almost anything could be made to work but i am not interested in fabricating one off airbox's etc. I quite fancy the idea of ABS, a more modern engine ( more powerful i mean) and all the modern dash with attendant rider modes etc. If this has been done already the guys on here will know about it. keith
