Mounting structure for an air-fuel ratio sensor in a motorcycle, and exhaust subassembly including same

An exhaust subassembly for use on a motorcycle, the subassembly comprising:

• an exhaust pipe having a side wall with a hole formed therein;
• a reinforcing member attached to the side wall of the exhaust pipe, the reinforcing member comprising a cylindrical collar with a threaded hole formed therein;
• and
• an air-fuel ratio sensor having an end cap with male threads thereon which fit in the threaded hole of the cylindrical collar;
• wherein said air-fuel ratio sensor is mounted on the exhaust pipe so as to be pointed upwardly toward a lateral center of said motorcycle, as viewed in front elevation of said motorcycle, in an installed configuration of said subassembly.
