You have both CBR600 RR as well as CBR600RR, both being the same vehicle, i think if you could merge the first into the second(which has more) and delete the old category?
That's not the only one. Suzuki's LS650 is listed as the Savage LS650 and the S40 Boulevard LS650, as well as an entry under the brand name "Savage" also the LS650. Makers that rename essentially the same vehicle are largely to blame.
yea cbr600rr has been the same model name since the beginning, dunno how that happened, let's hope they can sort it, helps to see all the vehicles where they're meant to be so you can see better fueling info for a wider range rather than halving them across two
