Can a 1989 Yamaha TZR 125 be derestricted?
Yes I have a 1989 TZR 125 that is derestricted and it hits 95+ with the powerband kicking in at 7000RPM, but f*** all below that. I also find there is a restrictor at 10500 RPM which stops the engine from revving any higher. Before it was derestricted it hit 80mph with power band at 5000 RPM.
What kind of engine does a Yamaha TZR125 have?
Fitting the appropriate powervalve servo will alow the best of both worlds. The engine will pull well, just as in restricted form, and then still give mental power at 8000 RPM. The TZR engine share a lot of its roots with the RD125LC. These engines are reliable and have plenty of tuning potential.
How old do you have to be to buy a Yamaha 125?
Many an aspirant 17-year-old was sold on the learner bike via the reflected glory of the bigger machines. The 125 was a machine that sold on image rather than outright performance.
What’s the top speed of a Toyota TZR?
The TZR handles and brakes well and is comfortable even on a long ride. In restricted form it is able to cruise at 60 MPH on the motorway easily. Fuel economy wise you should see figures well into the fifties. Top speed in restricted form will be about 75mph, and unrestricted models should see 90 mph when standard.
Is the Yamaha TZR125 a good looking bike?
The TZR125 is a good looking machine. If kept standard, the engines last a long time and give years of fuss free ownership. The UK model also has the powervalve (YPVS) engine, but powervalve is pegged in restricted position and thus can’t operate. In restricted form, the engine pulls well low down in all gears and has excellent spread of torque.
