2014年11月4日 · Prior to EICMA we had roughly speculated on the differences between the H2 and H2R based on mild visual cues. Now we have the specs to facilitate a legitimate discussion. Compression Ratio H2R: 8.3:1 H2: 8.5:1 Final Reduction Ratio H2R: 2.333 (42/18) H2: 2.444 (44/18) Rake H2R: 25.1 degrees H2: 24.5 degrees Trail H2R: 108 mm H2: 103 mm ...

2014年10月31日 · The ECU numbers show the H2 has a final drive of 2.44 (44/18) and the H2R 2.33 which could be 42/18 or 44/19. The H2R manual confirmed it was 42/18 If A = Success, then the formula is A = X+Y+Z.

2015年9月11日 · But considering its the same engine (minus a gasket, clutch & cams) that the H2 is capable of similar HP to the H2R, reliably,,, when set up right; Stage 2, DNA, full Brocks, PVC equipped H2 might be the smarter purchase. Of course the extremely limited #s of H2Rs is an advantage but $28k vs $50k for similar performance? Seems like a lot of the ...

2015年6月27日 · The R1 and Busa are quick, each hitting their speed limiter with plenty in reserve, but the H2 gets there much faster. From a standing start the H2 will reach its terminal speed almost half-a-mile before the Hayabusa, and cuts the Yamaha’s 0-180 terminal figures in half. The H2 will reach 184mph from a standing start in just 900 metres.

2017年10月7日 · H2R cams also allow more boost. So the H2R is making 24psi vs the H2's stock 15-16psi with the factory rev limit, and 18psi with the increased rev limiter to 13,999rpm. Add stage 2 gears and you have another 35-40+whp, add some drop in cams and you have exceeded the H2R. The R does comes restricted as shown, and is incredibly rich.

2018年1月7日 · H2 SX vs ZX14R On my second ZX14 now, a 2013 ABS model, and love the bike, but I really think the H2 SX SE will be my next one. I have mine kitted out for touring with Corbin, Givis, Throttlemeister etc, and I use it for scratching around local canyons and touring, and I think this new one looks to be a fine replacement, when the time comes....

2016年9月18日 · According to what he posted anyway; that's what he dyno tested a 2" header (which is larger than the H2R's) vs. the OEM H2 sized header. Imo the Vandemon system is the closest thing out there to the H2R exhaust. Not just because it's titanium but because the whole pipe looks identical to the H2R's in how it flows.

2015年2月7日 · The rev limit of the H2 is ~13000 RPM. The H2R is ~14000 RPM. With centrifugal superchargers, the boost rises with engine speed, so the H2R already has a boost advantage with the extra RPMs. I believe that the real secret to the restrictions of the H2 are the throttle-by-wire maps. Check out the main (full power) map from the H2 ECU.

2022年6月27日 · My stock 2015 H2 did 230 hp on a dyno after just woolich tuning. After H2R cams & woolich tuning I got 262 hp, but with much better partial throttle performance for on road riding. This site used to be buzzing with many knowledgeable gentlemen doing amazing things to the H2, most seem to have gone, or just quieter now.

2017年3月3日 · Even if the bikes aren't putting down the claimed bhp due to an overlay rich AFR; Kawi claims 310bhp for the H2R/326bhp with ram air (at maximum effect). H2 - 200 crank hp/210 w/ ram air. So Kawi claims ram air is good for 16bhp on the H2R vs. 10bhp on the H2 so only a 6bhp peak bhp difference...
