What are the color options available for this bike? And, how does the 4-valve engine influences the performance of the bike?

Hi Sophia Bauer, Thanks for your review and interest in the Yamaha YZF155 (R15 V4) ABS 2022. For the available color options, please check our website for the latest update as it varies from time to time. As for the 4-valve engine, it helps to increase the efficiency of the engine and the bike's overall performance by allowing more air/fuel mixture into the combustion chamber and also enables quicker expulsion of exhaust gases, resulting in higher RPM and more power. We hope this information helps!
