both bikes are race replicas..... some people just love that v-twin and others can't live without the inline 4. It comes down to preference.. If you get a chance to ride each of them you'll know what you like. Two different worlds!!!!!!!!!
Back in '00 the AMA allowed anyone with a twin to race a 1000cc against the 750cc fours. That was the main purpose of the RC-51 for the bike had less power then the Honda 929 & weighed more as the 929 was designed for fast hwy use & would then be the ideal bike if it was switched to 1000cc fours in racing. Get the thinking of Honda?
If you put out the money for all the kits, offered to RC-51 bikes then you could keep on upgrading the bike to be next to factory bikes. Most would not because of the price was simply ghastly plus being so late & so did their own. Then the advantage of the 1000cc twin against the 750cc four was dropped by the AMA & so the 1000cc fours took over as they have in AMA racing.
Hang onto the words of LDH for he does not sling any bull & knows his bikes.
Oh & LDH I see you have the CBR1000 with the best of gripers on the petrol tank. I will have to get at least two if not three sets for my bikes, but lost the e-mail address of the firms that handle them. Hink, Hint.
