Morning Dave, Yes the Bou bars are listed 4.5 inch rise, S3 bars fitted on your red 4RT are similar rise. Renthal have a 5.00 rise bar in black only and comes with bar pad. The Renthal spec sheet lists this bar
13mm 1/2 inch higher than the Bou bend bar, when I tried them did not think the 1/2 inch would make the
difference I was looking for but it did. No problem to try my bike at Craigs with the higher bars on, or
do you come over to the monthly Saturday trials practice day at Tong. Regards Richard
