If you say so Rick,if nothing to gain why do S1,X1,S3,XB9R and XB9S all have inverted forks on them.Hmmmmmmm,doesn't make sense.Nothing against the standard cartridge fork or anything,but I did this very same swap and it made some difference and more spring options.BadS1 | ||

Bads1...Rick has some validity to his reasoning. One of reasons the other bikes use the inverted forks is because there is less flex. This can be over come by adding a fork brace (I think Banke sells one). | ||
| Bads1 |
Banke doesn't sell one have there catalog but CrossRoads and BUELL do, same identical part about a $100 pricey little chunk of medal when I've seen full set of inverted forks go for $200-$250 on ebay if you have the patience. Also Kevins cool scoot would almost be identical just short of some rearsets | ||

Doesn't the M2 already have a fork brace? I'll run out to the garage but I think that's already covered. If you want to see the difference in fork flex, Go to your local dealer and (without drawing to much attention) Lock you knees on either side of the front wheel of an upside down fork bike (your choice). Now shake the bars vigorously. Now try the same with an M2. Which one flexes less? JT | ||
| Bads1 |
You are exactly right Jeff the parts you can buy from other aftermarket companys are just ment to make the bike look nicer.Oh and remember my bike is an M2 and I've had both type forks on the same bike.I'll take the inverted forks. | ||

What have almost all the Supersport 600's used? Conventional forks. The only real disadvantage is weight, as far as I know. | ||
| Bads1 |
Rick supersport 600 has to use them AMA rules won't let them change forks. But starting 2003 Kawasaki's new 636RR for 600 supersport has inverted forks and I think so will honda.Big liter bikes had alot more things that 600's did'nt have,in exchange it made them less expensive to get into.Kawasaki and Honda will both have 2 versions of ther 600's for 2003 I don't know about yamaha and Suzuki will do no changes for 2003 | ||

I think that while you lose preload, you gain rebound damping adjustment? Also having the larger tubing in the clamps, should make it stronger so there's less flex between them and the front wheel. PPiA | ||
| Rick_A |
From what I've heard...I don't have any irrefutable proof...the inverted forks are stiffer in every way but in torsion. There they flex more. I thought the M2 forks were 3 way adjustable. | ||
| Peter |
My M2 did not have rebound damping, but my S1 has. You mean torsion as in the "twisting" resistance of the tube? I don't think that would be an issue as the upper and lower sections of the fork legs can twist in each other anyway by nature of the design. PPiA | ||
| Bads1 |
My 2000 M2 when it had the Showa conventional fork it had rebound damping and spring preload.Pete what yer did you have that didn't have rebound damping? | ||
| Tavs |
What the M2's don't have is compression damping, which is what I need. | ||
| Bads1 |
Hey Peter is that a Hyper Pro rear shock on there, and how do you like it, looks trick?Sheeeeesh....I thought I had $$$$$$$$$ in my scoot you feeling all right? | ||
| Rick_A |
Peter...that's exactly what I'm sayin'. I personally wouldn't go to the expense of replacing a 43mm conventional fork for an inverted. If it's good enough for R6's, CBR600's, ZX6's, etc...it's gotta be alright. | ||
| Ken01mp |
wicked bike peter, very nice. but that part in your profile where it says, "top speed attained (mph)", yeah, yours is in KPH. its comes out to a ph below 160 mph. still, way cool ride. Ken | ||
| Bads1 |
Most people would'nt go cutting a frame on an M2 to make an S1 either but thats being Buellish.And like I posted earlier the 600's are now going to have inverted forks on them.Kawasaki and Honda for sure.These bikes companies would'nt do this unless it was going to benefit,first the sale,second the bike,third winning on Sunday,the factory race team. | ||
| Peter |
Bads and Tavs, You're correct. It had rebound and not compression. My bad. It's a Technoflex setup on the rear of the S1, but is the same as the Hyperpro. Ken01mp, We use kph over here. Sorry for the confusion..... PPiA | ||
| Bads1 |
Peter do they have a web sight for that shock and how much $$$$. thanks BADS1 | ||
| Rick_A |
Yamaha and Honda are sticking with the conventional forks. Kawasaki has gone to inverted. They're the only one's that made the switch thus far (in the 600's) for 2003. | ||
| Bads1 |
Did you know though that honda is also offering 2 I repeat 2 versions of there 600,look .again | ||

Upside down forks big advantage is less unsprung weight when compared with an equivalent right side up fork. Most of the flex transmitted through the chassis is through the triples into the fork tube. An upside down fork's outer fork tubes are much larger diameter (54mm in the case of the buell x1) and result in a stiffer triple assembly than the smaller 43mm right side up fork. Since the outer fork tube assembly is stiffer, you can get away with a smaller/lighter slider diameter as well (the Ohlins upside down superbike forks use a 41mm slider). 600's have always run right side up forks in the past since they were built to a target $$$$$ figure and right side ups are cheaper to produce than upside down. As economy of scales grow in favor of upside down forks and the 600 class continues to get more competitive, upside down forks will make more sense. As a side, from an engineering point of view, upside down forks are actually more logical way of designing a fork, and a lot of suspension guru's think the upside down/rightside up descriptions are acutally reverse! | ||
| Tavs |
BadS1: I assume that doing a conversion from an M2 to X1/S3 USD forks would involve the use of the USD upper/lower clamps, headlight support clamps, and fender. Are the axle and head stem interchangeable between the two? | ||
| Bads1 |
Tavs the axle was interchangeable but the head stem was an S1 stem that was already attached to the forks so I used that one.As far as using the M2 stem I'm not sure. Dana aka BadS1 | ||
| Rick_A |
IMO it's not worth the trouble to switch. That is all. | ||

The M2 forks with a set of Racetech 1.0 springs via Tat and gold valves are a lot cheaper than even the Ebay inverted. No they dont look as good and yes they come with a brace. But they will far out perform the stock inverted.BTW the suspension Guru's Andy and Cap set mine up with the aid of Courts rental car headlights at the 2K homecoming.Partially lubed with Lake Lawn bug juice attracted by Courts lights.I learned alot about suspension hanging with and helping the guys that day.

HINT: Get a list, call Tat, but the stuff and send if off to Little Mikely Kruger with your weight, riding style, etc. Or, I know Henrik has had nothing but good luck (fairly amazing considering how persnickity he is) with Traxxion Dynamics. Court | ||

fairly amazing considering how persnickity he is I resemble that remark  Henrik (and yes, I like the guys at Traxxion) | ||

Bads1, Website for Technoflex, but they don't appear to have separate applications on it. You'd need to contact them about price. I bought the bike with it already fitted. PPiA | ||
| Rick_A |
Oh...Bads1...I looked up that Honda info...they do offer 2 versions...and they both use conventional forks. The exerpt from Dec'02 MotorCyclist concerning the 2003 CBR600's I knew I wasn't crazy. | ||
| Bads1 |
Rick I truly thought Honda was using them.I had the writeup around the house.In there they did show both versions and the one did have inverted forks. The weight issue your totally right the cost right again ,put a invertad on there and cost of the bike go up and so does insurance because of replacement costs.Ya know them insurance guy's will give it to ya right in the behind when ever they can. |
