    When originally released the bike was highly acclaimed. 10 years on, and the KIPS system still has the ability to keep you entertained.
  4. Hi guys. I installed a 270cc big bore kit some time ago because I needed a new cylinder anyhow. Sounded like a great idea at the time. Everything I read was saying the 270 was the one to go for over the 290 because it revs more like a 250, the 290 was described as a bit disappointing. I was happy with it... I was a bit surprised to find the Vertex piston with it has only one compression ring. Not something that I saw mentioned anywhere. Went ahead and installed it anyhow, but after going through 2 pistons in about 60 hours I'm over it! I either want to get a stock Yamaha cylinder and forget about it or... Does anyone know if I can get a different piston to suit this application that has the regular 2 compression rings? If there is another brand of 270cc kit that uses that type of piston then maybe I can order that piston instead. The last piston I used was described as 23129A, which is 79.96mm size A.

    Vertex Piston Kit

    9 reviews

    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 engines 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 two-stroke piston rings sold individually; four-stroke piston rings sold as a set

    Very like the ease to innitiate to this bike. Good suspension setup, nice handling but a little lack in power. I upgrade it throught the years with this : Suspension : Stiffer .46kg/mm Factory Connection fork springs, Factory Connection lowering link, thicker FF5 Factory Connection oil in the HSSD. So the bike is now more stable without sacrifying is handling Engine : C4MX ported cylinder head, Pro Circuit camshaft and complete valvetrain, Yoshimura RS4 full exhaust, Moto Tassinari Air4orce, TUF 43mm Throttle body insert, EBC HD clutch spring, Twin air filters, PC racing Pro seal, removed backfire screen with a remaped ECM by Eddie Sisneros. I have now a better response, strong power everywhere with a lot of overrev. Control : Renthal twinwall handlebar, Zeta rubber killer, Zeta fold back lever, Motion pro revolver throttle system, Motion pro grips, Tusk footpegs. Drive : DID VT2 Xring chain, Supersprox stealth 48 teeth rear sprocket, Supersprox 13 teeth front sprocket, Zeta axle blocs. Body : Custom plastics mix, Custom graphic kit, Factory FX B4 seat cover, Cycra full armor skid plate, Work connection Holeshot device, Work connection Radiators braces, Black rims, Red anodized look hubs, Michelin tire, Moose spokes set, Zeta, breather, clips, plugs, washer and cap. With all this upgrade the bike became a real beast on the track.

    In love with the bike, the power, handling, looks. Everything. Got the red white colour but like the star racing bikes so got new plastics and graphics kit.
