rc engine OS SPEED B21 Ongaro Edition
TT motor 1/8th, 3.5cc.
Sold alone, without resonator or elbow. This new version OS SPEED B21 ONGARO EDITION (B2104) is the successor of the B2103.
This new version is of the long stroke type allowing a faster response to the relaunch at low revs. We can also note an increase in torque at mid-range as well as better stability when revving.
• The new crankshaft benefits from DLC treatment, ensuring longer life. The platter is balanced with a tungsten weight that promotes revving and a quick return to idle.
• The carburettor is a 22 E model with three adjustments. Air reducer 5.8mm/6.3mm.
• Round cylinder head is standard size and provides engine cooling.
• The new ABC-type piston liner is a model with three transfers + exhaust providing a gain in torque over the entire range of use. The piston is a machined model.
• The crankcase plug plate has also benefited from a surface treatment aimed at reducing friction with the big end and thus reducing wear.
• The exhaust transfer and the crankcase Booster channel have been redesigned to improve gas flow.
