I see that now tyga has pre load adjusters on there site... Anyone install them? Did they do much? Any info on these would be great
All well and good on the theory but actually the TYGA pre-load adjusters do work. We wouldn't sell them if they didn't. First thing I did with our MSX125 when we got it 9 months ago was to make some bushes that increased pre-load and it really helped reduce the diving under braking. Encouraged by this, we designed the pre-load adjusters and these offer the advantage of my bushes but with some adjustability and bling thrown in for good measure. Of course they don't transform the front end to GP spec but then again, it doesn't cost the price of a house or require a full on workshop to upgrade. I weigh 94 kg, and I'd definitely qualify as one of your porkies LOL Right, I'm off on my push bike now you've made me feel guiltyDid some math. Drew a few assumptions.
Without knowing the compression on the springs, I come up with ~41lbs/in each fork spring.
If we assume there's 1" of compression then I get ~26lbs/in each.
My static sag is ~1.65" with my 275lbs gut.
Could all be hooey here but the number I come up with say that porkies should look to fork springs before even considering these adjusters.
LOL Ok, now you're talking! I'll admit we didn't test this weight of rider, but every little helps and the more you preload the springs the better. Thicker oil too in theory (have you see the treacle they put in as stock?)94kg? Ha! You barely register on the pork radar.
They are a step in the right direction though.
I reserve my skepticism until I see/ride a bike with a 120+kg rider.
Well, we at TYGA are certainly not claiming that. We are just claiming they make a noticeable difference especially with diving and are a cost effective upgrade. Honda have made it difficult to upgrade the front end and this one of the gripes of the Grom, so hopefully they will listen to feedback and do something in the future about it.I can attest that I'm well at the end of the bell curve when it comes to potential Grom riders. But there are several here, in the initial run, that are +110kg.
To recommend fork oil and these adjusters as a panacea for the fork damping woes is a farce in itself.
