VHM Crankshaft KTM 85SX 2018-2024 / Husqvarna TC85 2018-2024 middle inertia with Light Weight Connecting Rod

This VHM crankshaft is designed with a much higher inertia for an improved handling and performance and a better balance percentage for less vibrations. You'll notice the high quality, as the runout is within 0.01mm and it can be rebuild many times without losing the strength and stiffness.

Besides that, this crankshaft is assembled with a special lightweight connecting rod kit (CRK1402) and must be used with the massive big end pin to ensure the best balance factor for minimum engine vibrations.

The connecting rod weight has 20 grams less weight compared to the OEM connecting rod and improves throttle response.

Through engine braking, standard big end hole of conrod deforms 0,015-0,02 mm oval, while our VHM conrod only deforms 0,005 mm (due to high strength material). In addition, this conrod is also super finished, which ensures a smooth surface. This helps prevent small fractures in the material.

• Better top over revolutions
• Better handling
• Higher corner speed
• Longevity and accuracy
• Less vibration

VHM crankshafts are made of high quality steel which had a heat treatment. The cranks webs are CNC machined and grinded to precise dimensions. The advantage of the heat treatment is that the crankshaft in totally will be a lot stiffer, because the resistance to bending of the crankshaft is much higher. This results in a much longer performance and the crankshaft can also be overhauled many times.

VHM crankshafts

With almost a decade of experience in producing special crankshafts, we are the expert in crankshafts for motocross, road race and karting engines.

We have manufactured crankshafts for the highest level of motorsport. For example crankshafts for road race bikes such as the Yamaha TZ125, Honda RS125, Derbi GP125 and Malaguti GP 125. Jorge Lorenzo, riding for Derbi Racing has won GP's in 2003 using VHM cylinder head and crankshafts. Ajo Motorsport from Finland also used VHM crankshafts for their Honda RS125 and Malaguti GP125 bikes.

In motocross, we have worked with Jan de Groot from Team Kawasaki Europe. Rider Mickaël Maschio (World champion MX in 2002) used VHM cylinder heads and crankshafts on his Kawasaki KX125.

Even for the Radio Controlled engines, many drivers and top tuner Chris Lukkasen from G4z is using the VHM crankshaft for the Zenoah G230/G270RC engines.

Many private and factory teams are counting on the performance and quality of the VHM crankshafts.
