I love this bike. Light, agile, super fun. It's the perfect single-track/trail bike. RK Tek performance head (https://2strokeheads.com/index.php/150cc-performance-heads-2) gives you about a gear. Pipe-guard. Fastway handguards. Fuel injected--fuel and oil go in separately and it mixes it for you. Electric start. Runs and rides great. Injury and age have me moving away from gas bikes, even my light 2-strokes, unfortunately.
