dave here.. i have an 05 busa with a Trac 10" over and 240 tire, RC wheels, pulled shock and went with strut ( i know.. old school / grudge style ) lowered and i also pull a trailer ?!! you'll get grief from alot of people on here about a big tire but hey, they'll get over it ! anyway, the Trac was a simple bolt on. yeh, had to relieve the frame on the chain side (and sprocket cover as well). but really a simple swap that i did in my drive by my self. took about 7 - 8 hrs just taken my time. adjustable links in middle hole and the tire has about 1" clearance to the taillight (remember the strut). i have over 15000 miles on it, with about 10000 of that pulling the trailer. NO PROBLEMS ! Remember... this is Prostreet/drag style, NOT roadrace !! it does have a harsh ride due to the strut but still not a bad ride at all ( same as chopper hardtail style). As always, a change in suspension/ arm extension / tire size requires getting use to . but still.. you'll be really surprised by how well the 240 handles . hope this helps ..
