Good evening. I have been staring endlessly at the "Furious" concept and I decided I wanted to order some clip on handlebars. I know the seating position will be terrible, I want it anyway. I was lurking the forum in fork tube size and it seemed the answer was 45mm. Then I saw 49mm. So I pulled out a caliper and measured the upper area of the forks and I got 54mm! I was wondering what the correct sizing for the fork tube would be to order the correct size clip ons??
