ADV350 - Ask me any questions

Hi ADV,
Got to say, i love the effort you have put into this thread, the detailed descriptions and photos you include are very handy and must be time consuming. for you. Good work.
Thanks! ... knowledge is power, and as Mr GTR @DavidFL himself would say, 'keep the power on'

I'll reply in the next few days.... but drop this info in here (assisted by a quick AI query by Proton Lumo+)

Best Resources for the Full Chart​

Two detailed PDF charts are available on Scribd that compile many more brands and products with measured viscosities:

  1. Fork Oil Viscosity Comparison Chart — broader brand comparison
  2. Motorcycle Fork Oil Viscosity Chart — includes additional shock fluid data
These are the most comprehensive visual references I found.
 
Sounds like you are prepping for a China trip? Do you mind me asking what sort of budget these trips run at (excluding fuel, food). Presume its a package.


Hi ADV,

The price for our custom tours with DT Travel vary quite a bit, next month we ride from Thailand to Everest Base Camp and this will be the most expensive tour so far in the 7 years ive been going on them, this Tour is $6700 Usd which basically includes everything except fuel & alcohol, we will be out of Thailand for 26 x days.................................we have guides that help us leave Thailand, enter and exit Laos and then China to Everest and return.


This tour is a bit different to the norm as once we arrive at base camp our bikes will be transported in an enclosed truck back to Jinghong in China whilst we explore base camp for a few days, then we fly to Kunming for a night, and then catch a high speed train to Jinghong to get our bikes and head home.


All meals supplied, all hotels which are 3 or 4 star (no shared rooms), usually 2 back up vehicles which are a pick up and a small bus, drinks and snacks availble free all day long, all excursions and entry fees included, max 4 days riding and then a sight seeing day, most of our trips are full without advertising, and many return customers, each tour around 12 to 15 riders.


The distances each day are not big km, usually based on stands up 8am and at the destination 3-5pm, depending on terrain 100 to 400km per day, DT travel supply SIM card for free, Win can exchange money at the rate on the day, I just take baht, some guys USD and change as required.


Some of our previous tours have cost alot less, around $3000 Usd or more, depending on itinary, all of our tours are custom designed by Win at DT Travel (Hanoi, Vietnam based) & Mike Gagne who lives in Thailand

Sorry for the late reply, @Cha Am Wayne

The official Honda workshop manual states 10w. No details on fork oil brand or cst in the official workshop manual.

I've just traveled 22k km on the Ohlins 10 fork oil and I was debating on changing it as it feels as if it's just ever so slightly going off. Same time as changing tyres.

Instead, I decided to push it out a bit further until yet another front tyre is due.

Next time I'm going to do the fork work myself due to the cock ups and sloppy ignorant guesswork by the bum chump boys (despite being provided with accurate workshop instructions on forks). I'll not say any more due to Thai defamation laws, so, DM me if you want a private chat about what occurred to piss me off.

Wow CST CM-SC13.

Awesome change to this wet season (on road) tyre.

Superb grip in the wet mountains of northern Thailand.

Holds the line very well even on occasional wash outs of sand and debris. Wickedly good dry road grip in heavy braking and also tight corners.

Faltered on snotty red clay porridge, in a road reconstruction area, but I think even the SC11 would have clogged up and struggled in that rediculous red gloop.

Parts pooled water at higher cruising speed blats down highways like a biblical character.

Purchased at the bargain price of ฿2,779 delivered for the pair of front and rear (including free pair of alloy 90⁰ valves) via Shopee store 320SP.

This is my first time riding on SC13 and I highly recommend them. Longevity mileage may be low on them though, so the caveat is, if you can buy them on offer, there worth a spin.

I decided to switch from the off road biased SC11 to SC13 because I'll not be risking exploring any single track clay trails in the wet season. I did get stuck into it (on the SC13) a week ago and busted my guts staying upright and never again (probably) hahaha.

I'll post again with a total km update when I change them. So good I just ordered another pair on discount in case I need to replace and still in the tail end wet season.

Here's a history of the company behind CST motorcycle and scooter tyres:

Cheng Shin Tire — The Story Behind CST​

Founding (1967) Cheng Shin Rubber Industry Co., Ltd. (正新橡膠工業股份有限公司) was established in 1967 in Yuanlin City, Changhua County, Taiwan, by founder Luo Jye. The company started as a modest producer of bicycle tyres and gradually expanded its range over the following decades. According to the company's own financial filings, it was initially established with just 178 employees and NT$6,000,000 in capital, specialising in motorcycle and bicycle tyre production.

Early Growth & Partnerships (1969 onward) In December 1969, Cheng Shin was restructured as a company limited by shares and began a technology and business collaboration with Japanese firm Kyowa Ltd. This partnership helped bolster the company's technical capabilities during its early expansion phase.

Becoming a Global Powerhouse  Over subsequent decades, Cheng Shin grew into the world's largest manufacturer of bicycle and motorcycle tyres. The company now employs more than 25,000 people and distributes its products in over 150 countries. Manufacturing facilities are spread across Taiwan, China (including Xiamen and Kunshan), and Vietnam, all operating to stringent international quality standards.

The Maxxis & CST Brands Cheng Shin operates through two wholly owned subsidiary brands that are likely familiar to riders:

  • Maxxis Tyres — perhaps the most widely recognised brand under the Cheng Shin umbrella, particularly strong in bicycle, ATV, and automotive markets.
  • CST (Cheng Shin Tire) — positioned as the brand covering a broad portfolio including motorcycle, scooter, ATV, car, truck, agricultural, and lawn & garden tyres.
The CST brand name has been associated with the company since its early days, but the formal rebranding to "CST" as a distinct consumer-facing identity is noted as occurring around 2015, when the company consolidated its branding strategy.

Scale & Market Position As of the mid-2010s, Cheng Shin reported worldwide revenues exceeding $3.85 billion (2015 figures), making it the 16th largest tyre company in the world and Taiwan's largest tyre maker. The company is publicly traded and continues to invest heavily in R&D, racing programmes, and manufacturing technology.

Motorcycle & Scooter Tyre Range Under the CST brand, the motorcycle and scooter lineup spans several categories:

  • Sport tyres — for street and sport riding
  • Adventure tyres — for dual-sport and adventure touring
  • Off-road tyres — for motocross and trail riding
  • Racing tyres — for track and competition use
  • Scooter tyres — for urban commuting and maxi-scooters

CST tyres are generally regarded as offering good value for money, sitting in the mid-range segment of the market. The company's racing involvement and decades of manufacturing experience give them credibility, though they compete against more premium European and Japanese brands in the motorcycle space.
