Honda

The Honda CBR250 series of bikes was produced between 1986 and 1996. It was a lightweight 250 cc (15 cu in) 4-cylinder, 4-stroke, and 6-gear sport bike capable of revving up to 19,000 rpm. The earlier models (1986-1993) produced 45 PS (33 kW). From 1994 on, the power output was reduced to 40 PS (29 kW), after a change in Japanese law

Initially these bikes were only sold new in Japan, and later the CBR250RR was sold new in Australia. But they can be found in almost any country of the world. In countries which have a 250cc learner capacity limit, the CBR250RR is one of the the most powerful 4-stroke bikes a learner is allowed to ride, hence their popularity.

The GSX-R750 is a sport bike from Suzuki's GSX-R series of motorcycles. It was introduced in 1985 and can be considered to be the first of the modern racer-replicas with many race-derived technologies and the looks of a Suzuki Endurance racer at an affordable price.

Yamaha advertised that the R6 had a redline of 17500 rpm. This is 2000 rpm higher than the previous R6 model and was the highest tachometer redline of any 2006 production four-stroke motorcycle engine.

It was widely reported that the YZF-R6's motor did not actually have this engine rpm redline level and was closer to around 16,200 rpm, but because of a deliberate tachometer error of about 8%, it read 17,500 rpm on the tachometer.

 In February 2006, Yamaha admitted the bike's true engine redline was more than 1,000 rpm lower than displayed on the tachometer than advertised, and offered to buy back any R6 if the customer was unhappy.
