must be broken

origional at easyparts 160 euro pfff.

anyone suggestions for alternative brand or aprilia type

it is a denso 129700
a little tour on ebay i found coils for aprilia rs 125 can i use this type?

H.T. IGNITION COIL APRILIA RS125 1996-2008 RX125 MX125 TUONO 55mm

bought one secondhand on ebay ,it seems the coil of RS125 1998-2003 is the same.

i bought a coil of a 125 leonardo.

if denso 129700 is printed on side of coil ,it must be ok..

30 euro incl PP.

i measure 12 KOhm between core and lead to sparkplug, must be OK.

spark is much brighter compared with the "almost" broken one,starts right again in one click.
