The stock pistons in your 750 H2 are a limiting factor if you're serious about performance. Wiseco's forged aerospace-aluminum pistons deliver the strength and precision required for sustained high-RPM operation, whether you're building a street-legal muscle machine or prepping for vintage racing. This complete kit eliminates the guesswork—everything you need to refresh your top end is included, and installation is straightforward enough for experienced DIY work.

Wiseco has spent over six decades perfecting piston design, and this K107 kit reflects that expertise. These pistons have proven themselves on track and street, offering the durability and power consistency that separates quality upgrades from cheap replacements.
