Description

For those of you who want MORE - the Polini Big Evo 96cc Tuning Kit MBK Nitro / Aeroxfor a fantastic price!

The kit contains a Polini Big Evo 94cc Cylinder and an MXS Racing GP Crankshaft (45mm stroke / 90mm conrod), a combination which will get your engine up to 96cc. The kit includes:

Polini 94cc Cylinder Kit "Evolution 2010" (44mm stroke) MBK Nitro / Aerox
MXS Racing Crankshaft “GP” (45mm stroke / 90mm conrod) MBK Nitro / Aerox
MXS Racing Spacer 5mm MBK Nitro / Aerox

The addition of the MXS crankshaft with a 45mm stroke (instead of 44mm) will get the Big Evolution cylinder's displacement up to 96cc turning it into one of the largest cylinders for MBK Nitro and Yamaha Aerox on the market.
It has a 90mm connecting rod for improved power transmission to the crankshaft and consequently improved performance.
With the right components (30mm carburetor, Hyper Racing exhaust and digital ignition) the kit can easily get more than 26hp!

You'll have to mill in the crankcase to make room for the cylinder base (d = 57.2mm +/-0.1mm, depth = 20mm) and the crankshaft (d = 77mm); manual is included.

Note: You'll have to adjust squish clearance when installing the kit as the crankshaft has a 45mm stroke and a 90mm connecting rod.

Straight out of our very own MXS Racing engineering department - MXS Racing Crankshaft "GP" MBK Nitro / Aerox with 45mm stroke, available here at Maxiscoot for an excellent price!

This engineering masterpiece was specifically developed for our MXS GP cylinders and is clearly a high-end "Hyper Racing" part. The use of top quality materials, notably HQ Tungsten counterweights, and excellent balancing are among its stand-out features. And we did not stop here - the 90mm connecting rod (10mm longer than original) is forged out of HQ steel, CNC machine-finished and then TiN-coated. It comes with a reinforced silver-plated small end bearing (12x17x16mm).

As a final touch, the "MXS Racing" logo and the serial number of the crankshaft are lasered onto one of the crankwebs.

As it has a 46mm stroke, you'll have to mill in the crankcase of your Minarelli horizonta to make room for the connecting rod (77mm); instructions can be found in manual.

Variator-side spline diameter is standard 13mm and compatible with most variators on the market.

For Minarelli horizontal / 45mm stroke - 90mm connecting rod - 12mm piston pin - 12x17x16mm small end bearing.

Item no.: P166.0111

Polini 94cc Cylinder Kit Evolution 2010 MBK Nitro / Aerox, 44mm stroke, (Minarelli horizontal LC, 13mm), the most powerful "Big Evo 2010" cylinder kit by Polini, available @ Maxiscoot!

The kit includes:

  • 94cc Aluminium Cylinder “Evolution 2010”, d = 52mm / conrod = 85mm, with 6 transfer ports and a bridged exhaust port
  • Single-Ring Piston, 13mm pin, d = 52mm (for small end bearing 13x17x17.7mm)
  • High-Compression Monobloc Cylinder Head “Evo 2010”
  • Gasket Kit for mounting and adjusting squish

Technically speaking, the Polini 94cc Cylinder Kit Evolution 2010 MBK Nitro / Aerox is a Nikasil-plated aluminium cylinder with 6 transfer ports and a divided, bridged exhaust port (new shape). It comes with a top quality one-ring piston (d = 52mm, 13mm piston pin) and a special monobloc cylinder head.

This kit is the biggest cylinder kit for scooters available at the moment, with a 52mm piston and a 44mm stroke, it ends up having 94cc displacement giving it a lot of torque. The kit falls into the "Hyper Racing" category and can reach between 23 and 25hp, provided that it is combined with the right components (Polini exhaust "Evo 94cc" or Roost exhaust BE94 and a 28-34mm carburetor).

Note 1: The exhaust flange has a different angle than the original (Piaggio flat type) and can only be used with a Polini Big Evo 94cc exhaust (same series) or a Roost BE94 exhaust.

Note 2: This kit can only be mounted with crankshafts that have a 85mm connecting rod, 44mm stroke and a 13mm pin (small end bearing 13x17x17.7mm), and you'll have to mill in the crankcase to make room for crankshaft and cylinder base.
