Hey guys, I'm new in this forum.

I have a 2008 Yamaha Yzf r125 with a 180cc cylinder kit. I'm not very satisfyied with the top speed, I got too grate acceleration and just keeps hitting max rpm's all the time, almost like i need a 7th gear. iI understand changing sprockets could help with this. Therefor I'm wondering if anyone got a recomendation for a sprocket setup?

Greetings Sweden

I have a 180cc and I run a 15 tooth on the front whcih is quite nice. It literally gives you that additional gear you're wanting and means you can cruise at 70mph at about 8k rpm, but it's geared for 85+ in case you need to overtake stuff. I recently tried it on the 14t again just as an experiment and whilst it was fun I felt I was missing a gear.

Hope that helps :)
