hi guys
is the hyperpro front end kit a lot stiffer than standard. Really hate the front end dive on mine. hit the brakes firmly and the missus on the back is nearly over the top of me (oops). Also want to lower front end but only got 30mm of play left before lower tubes hit triple trees. thanks

I went with Racetech springs and valves at the front end. I don't think the brand really matters.. any decent spring chosen to reflect your weight and riding preferences will be an improvement over that chosen by Mr Honda to be all things to all people. Same goes for the rear, I guess!

My suspension fettler informed me that a replacement spring for the rear of a 2015 bike was difficult, given the tapered spring and the limited space.. but re-valving did the trick initially, for solo riding. I run a Nitron shock now though, because despite the upgrades, the OEM shock didn't offer enough damping adjustment to gracefully cope with pillion + luggage. We should probably eat and drink less.  :033:

Cheers for that. I will for sure by the hyperpro front springs next month.

Re the rear a shock makes sense. Nitron get great reviews so may go that route. I'd be a brisk rider & the stock suspension I find gets squishy once it heats, particularly in the rear. Will keep you posted.

To be fair the chassis is quite good , it's a fun bike on twisty / hilly roads.

On Nitron's website I can only see they have rear shocks available for 11-14 models. Will the same shocks fit the '15 model?

I'm having the same issue where the bike becomes extremely wheelie prone with a pillion and minimal luggage and the preload adjusted to the hardest setting.

I might be going the non-remotely adjustable route as I am with a pillion 50% of the time and the other 50% i could not be bothered changing the settings for my London commute.

No, I don't believe so. I have spotted the same and wondered.. Mine came from a user of this forum on whose 2015 bike Nitron developed a prototype shock. Upon selling the bike he re-fitted the OEM shock and sold the Nitron to me. Subsequently, Nitron have not offered this model, so mine's apparently a one off for now. I do wonder why they decided against listing it on their site. You could always ask and see what their response is.

One thing I'd say about the Nitron on a 2015 bike is that it's extremely awkward to access the damping adjuster (it's a combined adjuster, doing both rebound and compression at the same time). The chain and swingarm linkage conspire to make it an awkward, messy job to get your hand in there to turn it.

You definitely need more compression damping then!

I also have a Nitron unit on my TDM, which I bought when I rode solo 100% of the time so opted for no remote preload adjuster- I did get the required C-spanner, but I cannot adjust it even with that, it's just too stiff and the spanner's too short to get enough leverage. But whatever.. it's only preload (ie ride height), when changing the load most import is the damping adjustment, which is the rotary adjuster at the bottom of the shock (for the basic road models).

Thanks for the advice. Tried to adjust the compression damping knob and it too appears to be in the highest setting possible. I guess it's either busted or a rebuild/regassing is required?

The damping knob? On the OEM shock, it's screw at the bottom of the shock that you turn.. not so much a knob. But either way, if it's fully turned clockwise, it's at the maximum setting. I doubt very much that it's busted, unless you cannot turn it anti-clockwise either?

Rebuild may help, but the best advice is to speak to a suspension specialist. If you're on the west side of London, I highly recommend PDQ in Taplow (near Maidenhead).. they know their shit! They also re-valved my OEM rear shock and forks, re-gassed the shock and replaced the springs in the forks. It came back a different bike, for the better! But, even after that the shock still didn't cope too well with the demands of myself + pillion + luggage, hence me buying the Nitron.

Sorry, mixed them up. Yes, the screw on the bottom of the shock is set to the hardest setting and the preload is set to the highest setting as well.

Took it to the guy that has been fixing up all my previous bikes, he took one look at it. "Yep, it's gone". Luckily enough the bike is still within the limited warranty from the dealer I bought it second hand, so they're going to replace it for me.
