ive had the rb since they first came on the market must b about 3 years and out the box they are amazing fast mine had 27bhp on jbs dnyo and was at least 10mph faster than my ts1 and lot quicker getting there it was amazing going from third into 4th, at 60-65 in 3rd ud change into 4th straight into the power band and take off even up big hills into the wind etc it reminded me of a old rd 250 i once had even sounded like one , but i now want a nice shakeless long tourer type of engine but i hav no funds so i had to try an see what i could do to the rb kit an so far its doing what i want , ive got it to run cooler ,crusie at lot less revs and save petrol !! and its very smooth capable of pulling a 4,6-4.8 final drive and could go lower in 4th, at speeds of 60-65 (proper speedo readings from a vapour unit lol) but i would say if i had the funds it b a ts1 for crusieing and rb for town rides or a rb with a 5 speed box ! mmmm
