"BBB" BOLO BIG BORE (PISTON ONLY)
The long awaited Racefarm "BBB" (Bolo Big Bore) is finally here! The BBB kit includes 58.1cc piston, ring set, wrist pin and locks. Race Farm BBB Cometic Head Gasket sold separately and can be purchased here.
With the help of Wiseco, a industry leading manufacturer of high performance Powersports products such as forged pistons, clutch baskets, gasket kits, connecting rods, valves, crankshafts, and camshafts, Race Farm was able to create a Honda Ruckus big bore piston unique from previous offerings. The big bore predecessor featured a flat top design, however the RF "BBB" features a .015" dish design, 41mm bore and comes standard with WPC Metal Treatment helping with the reduction of friction and improving wear resistance.
For the extreme, WPC treatment for the piston is also available at an additional cost (inquire by contacting firstname.lastname@example.org).

Tech Tip: This particular dish design gives the motor a slightly lower compression (without sacrificing power) allowing the "hardcore" the ability to maximize performance by taking advantage of the squish area and flame. You will have to do your own homework on this one if you want to harness the maximum performance from the BBB. Otherwise your standard cylinder job will do and its "plug and play" for the skilled enthusiast.
Note: This BBB is not for the elementary rider/builder it requires additional parts/labor including boring of the cylinder, replacement of your head gasket, etc. This part is intended for off-road use only and we are not responsible for any damages or injuries that may occur to you and/or your engine. This is a high performance part please use your discretion before buying, if you do not know much about engines and/or possible positive/negative results of installing parts of this magnitude please do not purchase.
If you need boring/plating done we recommend using the pros at U.S. Chrome. Wiseco and JE Pistons independently endorse them as well.
