The new DR-Z4S and DR-Z4SM feature a 398cc, water-cooled single-cylinder engine with modern fuel injection, and when combined with the other updates, it marks a significant evolution from the outgoing model. To unlock even more performance of the updated Suzuki, Yoshimura engineered this RS-12 Stainless Race Series Full System Exhaust. It provides substantial power and torque improvements, as well as leveling up the style and sound of your Suzuki DR-Z4. With a 5.5% horsepower boost at 6,640 RPM and a 2.8% increase in torque at 5,180 RPM, we think this is exactly what your DR-Z4 needs to unlock even more thrills as you twist the throttle!\r\n\r\n\u003c\/p\u003e\u003cp\u003ePerformance figures stated are reported with the USFS spark arrestor SA-21-K installed.\u003c\/p\u003e\r\n\r\n\u003cdiv class=\"tst-table gray\"\u003e\r\n\u003ctable class=\"tst-tb newTable\"\u003e\r\n\u003ctbody\u003e\r\n\u003ctr class=\"tst-tr\"\u003e\r\n\u003ctd class=\"tst-td\"\u003e\u003cstrong\u003eSystem Configuration\u003c\/strong\u003e\u003c\/td\u003e\r\n\u003ctd class=\"tst-td\"\u003e\u003cstrong\u003eSound Level (2000 RPM)\u003c\/strong\u003e\u003c\/td\u003e\r\n\u003ctd class=\"tst-td\"\u003e\u003cstrong\u003eSound Level (5000 RPM)\u003c\/strong\u003e\u003c\/td\u003e\r\n\u003ctd class=\"tst-td\"\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr class=\"tst-tr\"\u003e\r\n\u003ctd class=\"tst-td\" data-tstlabels=\"System Configuration\"\u003eYoshimura RS-12 Full System\u003c\/td\u003e\r\n\u003ctd class=\"tst-td\" data-tstlabels=\"Sound Level (2000 RPM)\"\u003e90.4 dB\u003c\/td\u003e\r\n\u003ctd class=\"tst-td\" data-tstlabels=\"Sound Level (5000 RPM)\"\u003e93.4 dB\u003c\/td\u003e\r\n\u003ctd class=\"tst-td\" data-tstlabels=\"Weight\"\u003e10.6 lbs\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\r\n\u003ctr class=\"tst-tr\"\u003e\r\n\u003ctd class=\"tst-td\" data-tstlabels=\"System Configuration\"\u003eStock system\u003c\/td\u003e\r\n\u003ctd class=\"tst-td\" data-tstlabels=\"Sound Level (2000 RPM)\"\u003e74.4 dB\u003c\/td\u003e\r\n\u003ctd class=\"tst-td\" data-tstlabels=\"Sound Level (5000 RPM)\"\u003e84.4 dB\u003c\/td\u003e\r\n\u003ctd class=\"tst-td\" data-tstlabels=\"Weight\"\u003e17.8 lbs\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\r\n\r\n\u003c\/tbody\u003e\r\n\u003c\/table\u003e\r\n\u003c\/div\u003e\r\n\u003cp\u003e\u003cem\u003eSound levels measured using SAE J2825 standard with installed spark arrestor.\u003c\/em\u003e\u003c\/p\u003e \r\n\r\n\r\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003e\u003cspan style=\"color: #ff0000;\"\u003eRACE EXHAUST:\u003c\/span\u003e This exhaust system is for closed course competition only and is not intended for public roads or land.
