I Have owned a Rieju 450 for 5 months and is total crap. Poor handling . Bad design gear lever and rear brake levers get bent or broken easy as get banged all the time also have lost a rear brake lever as come loose.Have had exhaust come loose, Hwad stock bearings come loose all the time, Bike is very heavy at the front and is hard to find grip with it. Rear sub fram comes loose every ride. The bikes are very poor made Rieju has taken a Sherco and fitted the yamaha engine without thinking about how it handles the engine is also lower powered than any WR 450 i have ridden .Also my rear shock has just failed . Very poor bike
