2002 YAMAHA R1 ECU FLASH PLUS

The 15-19 R1’s engine is fantastic but would need a little more down low to make it a class leader but up in the top end of the rpm range it flies and eats up gears almost unmatched. That’s a 5000 rpm power band that if you keep the tacho in, you’ll fly. The 2015 R1’s motor is obviously most suited for track use with that almost perfectly smooth and flat torque curve from 9,000 rpm right to the rev limiter. Though, to be honest, you probably do not need more. The current R1 is nowhere near as punchy from corner to corner on really slow twisty roads if rpm is below 7000 rpm. 98 R1 vs 2015 R1 speeds in each gear Speed at 5000 rpm Pretty much all R1s that came before, even the first of the short stroke motor R1s – the RN12 are stronger motors in the bottom end. This lack of low-end torque is exemplified by Yamaha’s relatively high gearing. The US Yamaha YZF-R1 variants that are specced for the Californian market missions’ standards can make as much as 10-20 horsepower less at the wheels compared to non-US spec R1s from Europe and Australia. It’s likely this whole in the power and torque curve is more to do with noise and emissions.Īs per above the short stroke motor is not only to blame as tough emissions control also means in certain gears and at certain throttle openings, the R1’s performance is not 100% as to meet stringent new rules. This can be mostly remedied though with a Decat exhaust and ECU flash or custom dyno tune and with the elimination of the servo motor that opens up one of the exhaust valves as revs rise. The extremely short-stroke motor does have its downsides though as power and torque have been sacrificed below 9000 rpm and are particularly lethargic below 7,000 rpm if compared to rivals.

The peak of 180 plus has certainly closed the gap and is some 20 horsepower up on the previous 09-14 Yamaha YZF-R1 generation. Peak torque comes in at 79 lb/ft at 9300 rpm. This is the most powerful Yamaha YZF-R1 yet.Īs you can see from the R1’s dyno curve, peak horsepower is an impressive 181 bhp produced at 13,500 rpm. There are no horsepower clams for ram air but we can expect between 5-7 horsepower at 180 mph!

The new motor revs to a giddy 14,300 rpm and makes a claimed 197 horsepower at the crank excluding the ram air effect. The shorter the stroke, the higher theoretically an engine and rev – torque multiplied by revs equal power,r and the R1 had lots of power, 197 at the crank to be precise! The previous model’s short 78.0 mm x 52.2 mm was replaced with a new motor with an extremely over-square 79.0 mm x 50.9 mm bore and stroke. To bring the new R1’s motor in line with its competitors, Yamaha decided to opt for an even shorter stroke motor from that of its predecessor. MotoGP bikes are supposed to be prototypes with no road equivalents but you could argue that the R1 is the closest thing to a MotoGP bike on the road.Īrguably, perhaps along with the Aprilia RSV4 and the Ducati Panigale V4. Visually it was quite different from the family of very distinctive R1s it evolved from and took on much of its design inspiration from Rossi’s Yamaha M1 MotoGP bike. In 2015 Yamaha released the latest YZF-R1. It barely made 150 horsepower at the rear wheels. The 09-14 Yamaha YZF-R1 also lagged a little versus some of its competitors too, especially in the US market where their emissions regulations are tougher. It took Yamaha until 2015 to respond effectively as their 09-14 YZF-R1, although an amazing machine was lacking somewhat in terms of peak horsepower compared to BMW’s S1000RR. The S1000RR caught the big four sleeping…. While we’ve seen models from all of the big Japanese factories lead the horsepower hierarchy at least once in the last 20 years, it has been BMW and their S1000RR which was released back in 2010 and has led the pack in terms of peak horsepower and straight-line acceleration. Litre motorcycles have been chasing big numbers with each new generation of machine one-upping the last in terms of peak power. Like all motorcycles that we plan to test, the Yamaha YZF-R1 will have its acceleration measured from a standing start in 10 mph increments all the way to its maximum speed. The Yamaha YZF-R1 will be the first motorcycle that Motostatz will measure against the clock. The 15-19 Yamaha YZF-R1 is the latest addition to Yamaha’s legendary R1 range, and no doubt the fastest motorcycle from the Hamamatsu factory to date.
