I saw the carbon tunnel at Hay Days on Sat. Very nice piece with a very nice price, $6100 and change Canadian for stage four with molded on gas tank and $8100 plus for stage five with all carbon body panels. Stage five was 50 lb weight loss I think and four was I think 26 lbs.
i have a friend who had one installed from vertical composites and it was just over 3g INSTALLED so i figured if the tunnel was around 1500-2000 it would be worth it. buttt
