Manufacturer Part No: PTB-113-ST
For use with 2007-current models with 4 3/8" stroke crankshafts. Can be used with 1999-2006 models with installation of 4 3/8" stroke crankshaft. Package includes new cylinders.  Case boring is required.
We think the 113 motor might just be one of the best all around combinations available for the Twin Cam motor.  Kevin uses one of these motors in their own FLHT Classic and believes it to be the ultimate touring motor.  The increased stroke provide better mechanical advantage through rod leverage and the results are higher torque figures at a lower RPM. With stock bore carb or throttle body, 2,000 RPM cruising is possible with plenty of power on tap through the whole mid-range.
If you want that 454 big block in a Camaro feeling when you turn the throttle, this is the way to go. 
110-120hp | 125-135ftlbs | 40+mpg

What an awsome motor! This thing just don,t quit. Very rideable, rode about 200 mi today about half on interstate, half on the twisties over look out mt. in chattanooga. on the interstate cruise set on 75mph, running about 2800 rpm right at the low end of my power band. twist on it and at the blink of an eye it is at over 100mphZIP!!! On the other end on the twisties and switch backs very responsive coming out of the curves lots of torque no need to down shift run most of it in 5th & 6th gear around 45-60 mph. My friends were impressed, the one that just put a 98" (kevins quote ) 'SQUAKING CHICKEN. Said he should have listened to me and gone ahead and bought HQ parts. Kevin did the build and tune and WHAT BLAST WHAT A BIKE! HQ!!!
