FEATURES

r4 18   85028   16007   24028
Conrod:
New R4/18 conrod, redesigned and made with a special aluminum alloy that allows it to have a high resistance while maintaining the lightness and performance of the previous R4/17.
  Crankshaft:
The crankshaft is grinded to increase the mixture flow and has a special shape to reduce turbulences inside the crankcase. The balancing is done by three inserts made of tungsten alloy and the inlet has a silicon filling to reduce the weight of the crankshaft to improve acceleration. The durability has been significantly improved with the DLC coating.
  Rear ball bearing:
Rear ball bearing:
The rear ball bearing has high quality ceramic balls to minimize wear and inertia to improve acceleration and fuel consumption.
  New compact carburettor:
The new three tuning needles gives a better idle and improves the ability of the engine to return to low rpm after throttling.

Sleeve:
The sleeve has 9 transfer ports and an exhaust with booster ports. The special shape and positioning of the ports improve the internal fluid-dynamics to obtain the maximum possible performance.i.
  Underhead:
The underhead designed to work with a mixture of 16% nitromethane (code 28038), but optionally the engine can be supplied with a underhead to operate at 25% (code 28025).
  Exhaust:
Improved internal machining of the crankcase drainage port to facilitate the expulsion of fumes.
  Cooling head:
New head, redesigned to improve the flow of air and thus increase cooling and ensuring an optimal center of gravity.

 

RECOMMENDED EXHAUST

51010 Tuned Pipe (EFRA 2015)
3 chamber polished tuned pipe, more progressive with lower fuel consumption

41015 Manifold
Shorter exhaust gives less acceleration, but an increased topspeed

41016 Manifold
Medium exhaust is half way between short and long,
generally used as a starting setup

41017 Manifold
Longer exhaust gives more acceleration, but reduced top speed
