Great, thanks for the info

I haven't tried the RRz but people in UK said there was some problems with the 2009 Model, front end is not good and the back end is bouncing.. is this correct?? and fixed in 2012??

I ride 09 many times with 50cc Reverse engine (lot of power)...i`m not a professional rider, just some races and "sunday with friends", but i never lost my front/back with right tires and pressure. Do u use PMT tires or SAVA?
2012 chassis gain mobility...something like DM 2010.

Most people here use PMT's. The reports I hear are from the some of the fastest guys in the UK, they started to use the RRZ but changed back to the RR.

If you want to improve you have to switch to cycling RRZ 3 2014 where they were greatly improved the characteristics of the old looms RRZ both through the corners of that straight-line stability.
It will cost a little more updating, but it's worth it in terms of reliability. Hello.


Example here on the Forum Marco22:

Buy beautiful grc rrz3 2014 with adjustable swing arm, larger radiator grc, grc increased pump, mechanical brakes grc, ammortizztore steering grc, hulls still to be painted .... wonder 1400 treatable, if you need without radiator or contact me.
without motor, carburetor, filter, muffler.

Hi, thank you for the information. My friends in England say 2009 RRz has problems with bouncing.. has anyone here experienced this?

I can't decide which bike to buy... RR, RRZ, Stamas or DM. Most circuits in UK are fast, usual gearing for 40cc liquid cooled is 7 tooth front, 64-68 rear.

Any recommendations for this? Most people here are riding GRC RR 2005-2008. Of course I don't want a disadvantage.

In Italy all people just say:
RRz 2012>>RRz 2009>>>>RR.
RR too "strong" chassis.
RRz a mixture about stability and mobility
RRz 2012-14, like an RRz 09, but better in all situation
