CBR125’s are cool little bikes, but they are way cooler with a big bore installed! We had this great little bike sitting here and came across an Athena 170 big bore kit and power commander and could not resist the temptation to install it What a difference! More power all over. Gives you just the right amount of extra zippyness to make commuting a more joyful experience. Also makes a great starter bike.
