My wife is in need of tires for her CBR600F2. Hs anyone tried the Tomahawk recaps yet? If so, what are your impressions? Also, the size that they have for the front is a 120/70-ZR17 and the CBR calls for a 60 profile. What problems would the profile change cause if any? While we are at it, what type of oil should I use on the gun in my tankbag on the way to the NRA meeting? ;-) TIA, Eric
