ENGINE 190 PISTON KITS •All pistons are heat-treated with a T-5 hardening and tempering cycle •All piston skirts are coated with a high-tech Molybdenum Disulphite coating for faster break-in time and increased piston life •Cast piston kits are gravity-cast aluminum alloy (not forged) with 18% silicone content, which produces an extremely light but very strong piston •Forged pistons are forged from 2618 aluminum for superior strength and durability •Forged High Compression pistons improve power and torque across entire rpm range •Big Bore pistons increase engine’s displacement, torque, and peak horsepower •Forged Replica pistons are forged OE replacements •Replica pistons and all rings are OEM replacements •Kits include piston, rings, wrist pin and circlips •Replacement 2-stroke piston rings sold individually; four-stroke pis- ton rings sold as a set PISTON VERSIONS Cast Replica – Cast OE replacement piston Cast Race – Unique cast GP style race piston with only one compression ring Cast Big Bore – Big bore stock compression cast piston Forged Replica – Forged OE stock compression piston Forged Big Bore – Forged OE stock compression big bore piston Forged Race – Unique forged GP style race piston with only one com- pression ring Forged High Comp – Forged high compression piston DIAMETER PISTON PISTON RING SET WRIST PIN CIRCLIP FITS MODEL (MM) VERSION KIT PART # PART # PART # PART # COBRA CX 65 07-09, 12-16 - Cast Replica 0910-4138 - - - HONDA CRF150R/RB 12-17 65.97 Forged Replica - - - 0913-0061 65.98 Forged Replica - - - 0913-0061 CRF150R/RB 07-09, 12-16 (high compression 12.2:1) 65.97 Forged High Comp - - - 0913-0061 65.98 Forged High Comp - - - 0913-0061 CRF150R/RB 12-16 (Big Bore)(high compression 11.7:1) 67.98 Forged Big Bore - - - 0913-0061 67.99 Forged Big Bore - - - 0913-0061 71.97 Forged Big Bore - 0912-0306 - - CRF250R Race GP 09 (compression 13.7:1) 77.96 Forged High Comp 0910-1762 - - - 77.98 Forged High Comp 0910-1764 - - - CRF250R 10-13 (high compression, 14.6:1) 76.76 Forged High Comp 0910-2596 - - - CRF250R 14-15 76.78 Forged High Comp 0910-3413 - - - CRF250R 16-17 (high compression w/ T-Box forged piston and DLC-coated wrist pin) 76.77 Forged High Comp 0910-4129 - - - CRF450R 09-12 (compression 13.6:1) 95.95 Forged High Comp 0910-2599 - - - CRF450R 13-16 98.96 Forged Big Bore 0910-3330 - - - 98.98 Forged Big Bore 0910-3332 - - - CR500R 85-04 90.45 (+1.5) Cast Replica - 0912-0197 2 - - HUSABERG FE 350 14 87.98 Forged Replica 0910-2595 - - - HUSQVARNA 250 SX-F/XC-F 13-15 77.98 Forged Replica 0910-3180 - - - 250 XCF-W 14-16 77.98 Forged Replica 0910-3180 - - - FC/FE 250 14-16 77.98 Forged Replica 0910-3180 - - - TC/TE 250 09-11 (compression 14.0:1) 78.96 Forged High Comp 0910-2567 - - - FC/FE 350 14-16 87.98 Cast Replica 0910-2596 - - - KAWASAKI KX65 00-16 (Big Bore) 46.45 Cast Big Bore - 0912-0199 2 - - KX250F 08-09 (high compression 13.9:1) 76.96 Forged High Comp 0910-1810 - - - KX250F 10 (+3mm Big Bore) 76.96 Forged Big Bore 0910-2587 - - - 76.97 Forged Big Bore 0910-2588 - - - KX250F 11-14 (Big Bore) 79.95 Forged Big Bore 0910-2059 - - - KX250F 11-14 (compression 14.5:1) 76.96 Forged High Comp 0910-2603 - - - KX250F 15-16 76.95 Forged High Comp 0910-3693 - - - 79.95 Forged Big Bore 0910-3699 - - - 79.96 Forged Big Bore 0910-3700 - - - KX250F 17-19 76.98 Forged High Comp 0910-5181 - - - KX450F 09-12 (compression 13.8:1) 95.97 Forged High Comp 0910-2606 - - - KX450F 09-15 97.95 Forged Big Bore 0910-3696 - - - 97.96 Forged Big Bore 0910-3697 - - - 97.97 Forged Big Bore 0910-3698 - - - KX450F 15-16 95.96 Forged High Comp 0910-3690 - - - 95.98 Forged High Comp 0910-3692 - - - 1 Replacment Cylinder Works Big Bore pistons. 2 Features new T-box forgings and DLC coated wrist pins on forged pistons with highest compression ratios for increased strength and performance.
