no it should be the same length as the standard s and firebolt.
the only difference for the Scg (or in my case the Low)
is the forks are shorter and the rear shock is shorter and has a shorter spring in it (yellow), blue are standard length springs, white are 09 and up Ss and Super TT, black are the pre 09 Ss (not sure about this one so anybody in the know please correct me because it may also be white) rear springs, and silver is on the uly X and XT
the fork diameters changed over the years too (not that it matters in this thread but maybe it will help others)
41mm was standard for all models up until 05 when they were upgraded to 43mm with the exception of the low and Cg that remained 41mm to the end. the 1125 bikes are all 47mm. sorry I don't know about the uly bikes other than in 08 they became 47mm but I don't even know when the model was introduced or what the forks were.
the swingarms were all the same length with the old style and then there was the uly arm the Ss\TT arm then the S CityX Bolt and SCg were all the same
or at least that's what I think it was off the top of my head...
