New HD200 owner rear suspension question
« on: February 04, 2018, 02:52:45 AM »
Hi guys and gals,

Just picked up a great 2007 carbie SYM HD200. First off love the scoot, however my girlfriend has just got her licence but is quite short and I was wondering if its possible to lower the seating position by lowering the suspension in the rear. I cant seem to figure out if it is set to the highest setting or the lowest. Can anyone help a noobie?

Cheers in advance

Your photo depicts the shock absorber at the lowest spring preload,(the shock absorber is still the same length with no weight on it/same seat height) which means it will compress more than the other settings with riders aboard the scooter, but this will only help very marginally in lowering the seat height, as you likely already have discovered...

If there's a lot of seat foam on your scooter, you could have it cut down and reupholstered...

I suppose it's possible ($$) to source a shorter set of shock absorbers and lower the fork tubes in the triple clamps an equal-ish amount to retain stock-ish geometry (handling, stabilty) but do so only if safe...(clearance of front and rear tires/fenders under full compression...no unwanted surprises🙃)

Lowering either end of the bike without doing so on the other, will change the handling characteristics of your bike...

Lowering the bike will lessen ground clearance and make it more likely to contact the road with a hard part while cornering..

It will also shorten the wheelbase (if you lower the forks) and make the rake angle steeper if you don't lower the rear end an equal amount (quicker to turn it, but you don't want too much...)

I know nothing about Australia, other than what I read in the book 'Dinkum Dunnies' in about 1977 (okay, I just looked at the pictures 🙄) but there must be plenty of auto upholstery shops  around there that could lower your seat for you.

Wow, thanks for all that info.

I knew this would be the best place to ask.

Looking to do this the easiest and cheapest way possible while still being safe so i might look into the foam in the seat.

Of note for ya.  It does not have the zip of the HD, but the Kymco People 150 & S200 do OK up to about 55-60ish mph and are notably shorter and lighter..also nigh on bullet proof once ya got 'em setup.

I was wondering if the cushion for the 2007 HD200 has any springs or is just soft foam?

I plan to start this project this week.

It seems to depress quite a bit leading me to believe it is very soft and I am concerned I may damage the seat by cutting away too much foam.

I watched the video you linked (thanks for that btw) and his seat seems a much more dense material than the hd200 has.

Anyone know how the seat is put together?

finances do not allow for another bike at this point however that's the dream  :)

I did have an Ikonik Legend 125 but that is gone now. Got rear-ended and totaled the bike a week before Christmas last year.
