Hello! I have hit 10,000km on my 2014 DRZ400sm and have some questions. 1. What kind of chain do I need to get? I am going be buying a bunch of new parts in this order with my chain and one of those parts is a spare sproket to give me more low end torque or wheelie power I was going to get a 14 tooth front sprocket. I dont know mubh about changing sprokets other than less teeth in the front is more wheelie power and more teeth in the rear sprocket is more wheelie power. The riding I do is mostly street. I do go offroad in the summer but 80% of the time she is a pavement princess. I ride highways alot and mostly sit around 80 - 100km/h. I would love to hear anyones opinions on the 14t sprocket change and am open to other suggestions. Ideally if its not the best for a full time change I would like to swap between a 14 and 15 for days I want to wheelies and days I will be mainly just commuting. 2. Do i need to replace the rear sprocket with the chain? There are aluminium and steel ones available. whats the different and advantages of one over the other? 3. What is the different between X and O ring? This is my first experience with this stuff so I dont know any knowledge and am all ears to any info I can get. I dont know what I would do without you guys on TT. This is by far the best knowledge in the world for DRZ400. because of you, I have been able to learn everything I have dreamed of and am able to do the maintenance and put in new parts myself which is something I ahve always wanted to gain te knowledge of. So thanks! You guys rock! Happy and safe riding folks!
