So you guy's don't think this is do-able on a TLR??? What are the problem VS the TL??? I may concider this mod for my TLR over the winter if it's feasable.....opinions? parts needed?
Unfortunately I think not Dean.
I have the swinger and the rim laying around but the TLR's frame is narrower and there's nothing th shave off like on the S...

If you ever get it done I'll buy you a case of beer and start again on my own bike :)

Certainly not with the Triumph swingarm, you would need to reduce the width by over 5mm each side which would need some serious cutting and welding etc

Then you have problems with the rearsets touching the Bow in the arm on the L/H side etc etc

You can use a Honda Bros swingarm or even others if you choose, but the 955i is the only one that kept the same wheelbase and had the hole for the rear header in the right place etc.

If i did another I would consider making a jig and make a tubular alloy arm from scratch and also get the bottom shock mount lower so I could fit the 916 shock and rocker, but pigs might fly first before that happens :coocoo

Some more pic hoaring without the pink bottle LOL

the pipe work is every bit as impressive as the swingarm.

It was a few years ago when I was at my fighting weight and a little missrepresentative of my current stature which misslead a few people at the BMF rally this year :laugh

Hello Sam

If you look in the frequent mods section at the gold valve installation for the Showa TLR conversion it will give you a 2 speed compression valve stack that will help your suspension guy sort your Penske. The tlr race bike has an 1150 lb spring which is stiffer than what you are using so you can probably go a little softer but that setup is awesome on the racebike. The TLR showa is also more progressive because of the angle on the shock than the Ohlins conversion for the TLR. Took me a year of testing to get the Showa TLR with the Racetech gold valve in the ball park but now I would put it up against anything. Hope this helps you save some time.

Thanks Doug

Just had a read, thankyou :)

I've not had any time to dial in the suspension yet, my ride was cut short when the can blew appart. Been waiting one and a half weeks for a new Ti sleeve to arrive :banghead

I leave the shimming to him, he gets it pretty spot on first time around. The Internals of the Penske he built me as some special high speed valving for the direct mounted shock option :O We settled on a 900lb spring as the 800lb give a little too much loaded sag and I want it to be a bit stiffer than normal for a bit of trackday riding and also to able to carry passengers etc.

I've not even touched the damping positions yet, Once I get the can rebuilt and a few other teething problems sorted I can go get a good few hours in the twisty's and have a better idea of where it's at :confused

direct mounted shock
How does a showa on a link (TLR penske layout) relate to a direct mounted shock. (TLR Ohlin's) :confused ..Surely the valving is totally different due to shaft speed and the link curve. :O

Bike looks ACE :thumbup :thumbup

Yep, I was still wiping the sleep out of my eyes and never spotted the obvious :devious

Doug, your shim stacks will be very different to mine, the shaft speed of mine is twice yours and although not ideal can be overcome with the trick high speed internals of this particular penske. He did explain what was different internally to me but I wasn't really listening as I was looking at his other jobs he was doing :devious

Apparently only Penske has the patent on this, which is supposed to be better than the Ohlins solution(the only other one who specialise in high shaft speed damping in direct mounted shocks)

Anyway it goes up and down and hasn't chucked me off yet LOL

I miss the pink overflow bottle! :rant :laugh Did you figure out a new baffle to sort the deafening thunder?

IDid you figure out a new baffle to sort the deafening thunder?
2 Sleeves arrived today from different suppliers, one plain Ti and one Stainless, so tonight I will rebuild the can probably with the Ti sleeve, I decided against the rainbow effect, too tarty and most of which would have been hidden anyway.

The sturdier sleeve should quieten it slightly but I've not worked any more on the DB killer yet. I'm not sure how long it was starting to blow appart and maybe not that loud after all :laugh

Although I am shortening the can 25mm or so to bring the tail pipe flush with the rear light to look better.

I will play with the DB killer but not a high priority until I have a bike to ride first :confused

Maybe I missed something but was sure you are using a direct acting shock setup which is what my Showa conversion on the TLR is, I know your shock is more vertical than the TLR direct setup but cannot see how it would be double the shaft speed. Anyway I am sure the Penske will have a 2 speed valve stack on the compression side which will work just fine once the stack is in the ballpark. Nice thing about the deluxe Penske is the external adjustment for low speed compression, on the Showa I had to take the shock apart and change the shim stack internally which is why it took me awhile to get in the ball park. Also I understand the current Motogp guys have virtually no rising rate in there linkage so in essence it works as a direct acting shock, all I know is the direct acting setup is nice when its dialed in.

I thought your's still retained the TLR linkage Doug ? If not, forgive me it's been a bad day :confused


Billy, I'm supprised you could hear mine over the noise of your rev limiter and squeeling rear tyre LOL

No problem, the TLR Showa conversion is direct acting like an Ohlins just retains the ability for ride height adjustment because it uses the upper stock TLR yoke setup, unfortuneatly it is a permanent conversion due to having to grind the frame for clearance. Anyway I will be interested in your comments on yours after you get it setup I personally have grown to hate linkeage type shock setups. Think the motocross guys have been on to things for years just takes awhile for us sport bike guys to catch up.

Us MX guys use linkage for our shock setups:thumbup

(all except for KTM's design which doesn't work as well as the rest - dunno if its a design issue or an execution issue - but they had top notch suspension prior to going linkless and have been bottom of the pack since...).


There have been some truly horrid linkage setups, but I think the design is sound and its certainly dominating the mx industry. I really like the simplicity and ease of service a linkless design offers and would probably accept a small trade-off in performance (i.e. I wouldn't avoid ktm because of it) in turn:)


I'm still wondering when sport bikes will start using twin-chamber forks and when separate high-low speed damping will be common place. It would also be really nice if sport bike forks were put together like dirt bike forks (no need for a spring compressor)....

One plus point from the can shitting itself was that is where most of my rubber stuck and now i don't have to clean it :laugh
