First step is to always disconnect the PC first and go from there if needed.!

Hi HzE, welcome! If you use the F4/F4i shock w/o a spacer the rear end will be dropped 30-40mm because of the ratio factor(something in the 3-4 to 1 range) and your not that short. Yes if you would then drop the front end a similar amount you could maintain most of the bikes balance, but again don't think you want to lower the entire bike over an inch. Spring wise, the stock vfr spring is too soft(15.3kg) and the F4/F4i is softer (around 14kg). I suggest you at least change out the upper mount bolt to a longer one (caution a standard bolt head will hit shock w/o grinding or using a flat head bolt) and at least add washers to gain the length needed. Install a 17-18 kg rear and .85 - .90 kg front springs. I think you can control the stiffer spring with the adjustable damping of the F4 shock, ideal no but worth trying on a tight budget. BR

Nice Write up!!! Thanks I also replaced the front CCT w/o bleeding out coolant, can't remember if I move the throttle bodies or not. I have pics somewhere. BR

That's what I have on mine. If I went to radial calipers with some adaptor brackets for my current forks, I could use 330mm rotors, but that's not only $1000 all-in, but also a bit overkill. And they hang off a set of Ohlins forks to boot!

There should be one somewhere here! Be sure to pull the rear wheel and use a jack to move the SSSA up and down as needed thru the shock replacement process. If i remember correctly you jack up the swingarm all the way to pull the shock out. Enjoy and good luck. BR

There is a guide for a 5th gen: http://www.vfrdiscussion.com/forum/index.php/topic/6970-how-to-install-an-ohlins-shock/ I don't believe there is a significant difference between 5th and 6th gen for the shock, but I'm not 100% certain of that. If I recall, there really isn't much different between the two except maybe access to the top shock bolt, but I did find it easier to remove and replace the 6 Gen vs. 5 Gen. Also, although it would make the shock replacement easier to remove the headers like in the tutorial above, I was able to R/R both the 5 and 6 Gen shocks without doing so. This does require moving the swing arm up and down for easier/better access to get the shock in where it needs to go, in this case a helper would make it an easier job, but if you have a scissor jack like the one in the tutorial, that should work too. Yeah, only real difference is length where the 5th gen is close to 1/2" longer.

Obviously a Penske or Ohlins valved for your weight and bike with the proper spring is the best way to go, but there's many options between stock and Ohlins. Check out: http://www.vfrdiscussion.com/forum/index.php/topic/19712-vtec-shock-options/ A f4i shock has been used many times on vtec's. Many folks have been, but do Not be talked into a 929 shock on the 6th gen, it's a much better mod for the 5th gen.! you can get the 929 shock in there, but it is NOT ideal for that installation no matter what your told. Also do Not just do one end of the suspension as it will only magnify the short comings of the other end of the bike. BR

Hello welcome and congrats.! Stock spring rate is a slight 15.3kg . Your weight alone should be seeing a 21-23 kg spring. I would suggest you buy a CBR F4i shock a get a 23kg spring from Sonic Spring and grab a set of 1.0 fork spring s while your at it as a minimum. Br

I have a set of later ST1300 cables and I'm guessing they might be 2" longer then stock VFR's. Not much gain IMO.

Bump for the mother of all bar mods! BR

Someone want to update this???

Welcome to VFRD and do post up on your results! BR

Yes! Ran 5th on 6th no issue other than lost capacity. there's a nice rh VTEC in our classifieds now.

Looks like your working on a 5th gen VFR 98-01 which Don't have CCT's and Not the 6th gen (Vtec) 02-09 . What year is your bike? BR

TOROCharger!!!
