Just as mark_swart commented above me to i found it's mostly just the stock spring rates that are way too soft for todays tracks and jumps. I personally don't understand guys that put modern suspension on vintage bikes. You either want a vintage bike

No, they're not available separately. And they are a pain to remove too...there is a o-ring underneath which makes it a real pain to remove them. I had one pair re-anodized as they were too scratched. Those first USD forks need a good service as they ... more »

Here's a copy of the '89 Mugen catalogue. Mugen didn't just offer the famous engine kits but also upgrade kits for suspensions. What most people know are the internal kits for the traditional 43mm forks but they also offered the USD setup complete with

That's the '89 Mugen forks which came with that red-anodized collar and with adjustable rebound I have 3 such Mugen forks fiitted to all my 89s. Big difference to those first stock upsidedown forks...and leaps better than the stock conventional forks.

Yes - on my HPP engines i actually prefer the Tomasin R&D exhaust as it revs a little further up than the Messico. I just like that extra overrev paired to that insane pull up the very top it offers. Next in line would be the Messico which is a great

As mentioned above me too i bought a Pro Circuit thinking it must be a great exhaust...well - not soo! Big disappointment. I really did just 3 laps and switched back to the italian Messico instead...oh boy-what a difference! The PC felt like riding a

I have best results with a 38mm Keihin PJ. Huge improvement over the stock 34mm ! I combine it with Mototassinari Vforce3 reedblock and also added this spacer to the ATAC chamber for better low-end. I tried a 38mm PWK Air Striker but it's no better,

I will only say this much: there's not much guys selling such parts let alone swingarms for every year... But as we can see you run the risk of having a rather expensive Banana holding your rear wheel. I wouldn't mount those parts unless you put the

I don't know for sure but i'd say yes - those were VRP parts. VRP also did HRC swingarms back in the day and still did aluminium parts for HRC in recent years.
