I bought a 07-08 R1 last June and since then I left the bike stock. I have a list of mods I hope to do to this bike, I'm sure you can imagine. I'm undecided about a few options, & I'm here to get educated about things.

I'm considering installing lowering links in front, and swing arm extenders in back. I'm wondering how this affects ride-ability, handling/cornering, or any other changes I should expect. I love the R1 for it's agility & don't really want to change it too much.

I'm considering a 2" drop in front with Vortex lowering links.
Also a 2"-3" stretch with Roaring Toyz or Yana Shiki adjustable swing arm extenders.
I do like the look of a mild custom street bike.

A little about how I ride.
I live in the Berkeley hills near Grizzly Peak motorcycle wall.
Riding twisties is on my way home. Most of my miles riding are not in canyons & corners.
This bike will not be drag racing any time soon.

What are the real pros & cons of this suspension change?

If you aren't drag racing, do NOT stretch the bike. There is no functional reason to stretch a bike except to keep the front tire down, and it will make the bike handle like poop and make you look like a poser in the process lol...

From somebody who has owned more than one R1 at once, one being stretched and one not...the stock wheelbase bike is always WAY more fun to ride on the street. A slammed and stretched liter bike is no fun lol.

And I love offroading too :D Got a broken xj to prove it lolz

Lowering will not affect the cornering too much but once you stretch it out, then it will change the handling on the twisties. It will be a little harder to corner. Bad arse on the dragstrip though.

Are you high? Lowering will effect cornering by a MASSIVE amount. Not only in ground clearance, but with suspension geometry. People that think lowered bikes corner "fine" are not taking the corner at an even remotely aggressive speed. If you lower and stretch a bike and are not a SERIOUS drag racer, you are a poser squid. Changing vehicle dynamics in the name of looks and not performance is not a good idea. Are you 4 feet tall? In that case you don't need to lower a bike. If you not looking to cut 1.6 60's you don't need to stretch it either. Hell, I launch at 8K and mine is neither lowered or stretched.

In addition to that, I think you might have a hard time lowering the front of the bike with Vortex links.

I lowered bikes from my CBR900, '99R1, 'Busa and now my '07. Feels the same to me. Until I stretch them out. Then it will ride like a truck. Maybe being a drag racer, I'm not as good as you ride in the corners. Sorry, I don't do drugs so I'm not high. Just my 2 cents.

Sorry to sound so abrasive, but I sell motorcycles and see this kinda stuff everyday. I just feel strongly about it. From your point of view, I could see where you would think they handle fine, because that is what you know. I get to ride new stock bikes every day, and they just handle SO well I hate to see people screw that up unless they have a goal like a dedicated drag bike.

No problem. Yes, I'm a dedicated dragracer. I like winning rounds, plaques and trophys beside a little cash and bragging rights. That is why we do what we do. For the purpose. My Shadow's suspension is untouched and that is what I ride daily slowly on the twisties cause I'm old. :lol
It must be nice for you to get to test all those new bikes.

stretching an R1 is gay as hell IMHO. Makes a waste of a perfectly good bike.

i have set my bike up all 3 ways stock to lowered and lowered and stretched. it corners like a champ stock and pulls the front wheel super easy. lowered it still corners very good you just have to watch your feet when your in the corners hard. front end stays down pretty good. but when you stretch it the bike still corners ok you have to watch speed bumps cuz you will probably scrape your headers. that goes for lowered bikes in general. you can tell it turns wider. but i like them all i usually only leave it one way for a few months and change it up. my personal opinion is do what you want and find out for your self. you can always sell the parts if you dont like it. the best thing to do is see if you can find some one that has a lowered or stretched bike and ride it around a little. even if its not an r1 just to get the feel. o and the handling depends alot on suspension set up too. EVERYONE HAS THERE 2CENTS SOME WILL LIKE IT AND SOME WILL HATE IT. the people that talk bad about lowered or lowered and stretched bikes have probably never even rode one. so try and find out for your self if you can and form your own opinion.

U dont have to be a drag racer to want to stretch and lower ur bike if thats what u want and it doesnt make u a poser...if thats the case all the people riding around with aftermarket steering dampers or aftermarket rearsets that dont stunt or roadrace are posers to ...not everyone wants to go 70-100 miles and hour in a curve and scrap there knee and elbow on the street just to show off or say they can...unless ur going to try to ride on the street like u are on a road race track u can lower and stretch ur bike and keep up just fine...its only when u are really trying to push it past further than u should be pushing it on the street would u have any problems...i am a motorcycle mechanic , drag racer, and a street rider and i ride all kinds of bikes as well and if u ride the dam thing u can make turns fine on the street...no u wont scrap ur knee but u will get through there in a hurry just fine...
put it this way i have a dumb ass friend with a hayabusa with 8 inches and a 330 tire on it who has total disregard for the fact that a 330 is for show and rides the hell out of it and will still go 75mph and up in a curve...yes if he didnt have the tire he could probably go faster but the point is it can still be done stretched ,lowered, and fat tire kitted...

so do what u want...and u will still be able to ride the hell out of it especially with just 6 inch extensions

p.s.
u put lowering links in the back to lower the back. to lower the front u do that with the forks by either sliding them up in the triple tree or actually going inside the forks and changing the internals...

either way make sure u let a professional do it....

If you don't play in the twisties then I guess I don't see the harm in stretching it.

Personally, if I wanted a stretched bike (obviously for going fast in a straight line) I would start with a better foundation like a newer ZX10r or GSXR 1000.

I love the twisties and owning a bike that handles better than most street bikes.
