125 RT revolution

[badseed]

What is the normal rev/min range to use the motorcycle? I generally use around 6000 and some people told me that it was too much. The highest written on the screen is 12000. If I use it below 6000 It becomes to weak.
thnx

hello

my rt125 is geared 16 front sprocket and 52 rear and
stock is 16 49
60 mph is 9000 rpm and i run it on the highway
between 55 and 60 mph but on a trip once i ran 9500 to over 10000
rpm that =66 plus mph
for almost 2 hours and did 225 miles in 5 hours

it has 7500 miles on it and still runs fine
the motor has about 20 hours of interstate high speed on it ie
9000 plus rpm for 5 and 6 hours at a time as i take long road trips on it
it is the sweetest running motor i have ever owned i have been riding
motorcycles 46 years

Depends on hw much you want to pay.

There's this site, MZ-Faber.de, but this doesn't work for me personally (shipping to North America + Euro-to-US exchange rate + weird banking methods = too much money and hassle).

KSport in California has some bits and pieces, mostly a cam kit and a sprocket upgrade (courtesy of Sprocket Specialists).

You can get suspension upgrades from Wilbers (USA site here). For the SM (and possibly the SX), you can get the Technoflex 630-603-00 rear shock, and 601-278-00 fork springs.

Powroll makes exhausts for the SM/SX/RT, using Supertrapp exhausts and a cross-pipe.
