The Carrillo MX9031C is a high-performance piston kit engineered specifically for 2006-2010 KTM 250 SX-F motocross applications. This oversize piston features a 79mm bore (+3mm oversize) with a 54.8mm stroke, increasing displacement to 270cc for enhanced power output.

Key Specifications:

  • Bore Size: 79mm (+3mm oversize)
  • Compression Ratio: 13.5:1
  • Stroke: 54.8mm
  • Displacement: 270cc
  • Material: Forged 2618 aluminum alloy
  • Piston Number: MX9031C
  • Compatible Rod: 5415
  • Pin Number: S630-1650-13C
  • Ring Set: CP7900C (79mm 2-ring pack)

Premium Features:

  • Fully CNC machined for precise tolerances
  • Balanced to +/- 1 gram for smooth operation
  • Double forced pin oilers for superior lubrication
  • Forged from high-strength 2618 alloy for extreme durability
  • Designed for maximum performance, horsepower, and reliability

Complete kit includes piston, ring set, wrist pin, and clips. CP-Carrillo pistons are manufactured in the USA and represent the gold standard in motocross piston technology. Due to the high 13.5:1 compression ratio, 110+ octane race fuel is recommended for optimal performance and engine protection.

It is very nice to know that there's more than one online store that has cheaper prices for hopefully the same durability.

Wish I purchased for last season, boat steers with one finger now.

fine

the website isn't loading correctly. I have ordered through here before with no issues. today i couldn't change my shipping option and it loaded the screen in text only. the price is still good, so its not a huge deal

it'll be a 5 star when i have the product
