2014 Specialized Brain to 120mm?

Question – Rockshox SID B (2014) has travel from 80, 100 and 120mm. My Epic with Specialized Brain is 100mm. Can I upgrade this to 120mm?

Short answer – No

Long answer – No, the Brain Cartridge connects the fork Upper and Lower sections and has 112mm of travel at best and really only 107mm usable.

If you get rid of the Brain damper and buy the parts to convert it to an RL, RLT or RCT3 damper, the the uppers and lowers are seperate.

Also – if you are wondering how to disassemble your lowers, you need a 10mm box wrench. No shortcuts.

Versys KLE650 vs VStrom DL650

Review from someone that has owned both.

Summary

Despite very similar specs, these are two very different bikes.

Versys is more “fun” to ride round town, but not so comfortable on longer rides in stock form.

VStrom is better to customise and tour on. it has ABS.

 

VStrom Versys
Vague Steering (until modified)

Falls into corners like cruiser

Smooth motor @ cruise

Vibey motor @ high revs

Motor torque has OK pull

Won’t wheelie

Limited tyre feel

Good seat U shape

Great dash

Dull brakes

ABS available for only $500

Limited leg room

Lots of Acc’s available

Long front guard

Great headlights

Weight more on rear wheel

Long, very long wheelbase

Brilliant 350-400km fuel range

Sharp at low speed

Tips in like sports bike

Vibey @ cruise

Smooth at high revs

Motor Pulls like a train

Wheelies (lots)

Harsh suspension, ok feel 

Seat tips forward

Lousy minimalist dash

Sharp brake feel

No ABS in Australia

Good leg room

Limited accessories

Front guard too short

Headlight average

Neutral weight balance

Short wheelbase

Average 300km fuel range

The Versys had Michelin Pilot Road 2 tyres – wonderfully sticky. Despite having very similar dyno charts, the Versys definitely feels more torquey and pulls much more when over 160km/hr. The Versys suspension is far to harsh on less than perfect roads, even after tuning it as far as I could. I find this a major failing on a bike sold for it’s long travel suspension.

The VStrom tyre choice on road is not as sticky, but has a better range of off-road tyres.
The VStrom with Racetech fork valves and springs is a much better beast than stock, with steering sharpening up, and brake dive disappearing. Before it was a bit soft and somewhat harsh.

Drag racing them side by side shows the acceleration from 1st to 6th is basically exactly the same. Seat of the pants though feels like the Versys is MUCH snappier. Ass Dyno wrong again.

Braking is interesting. The ABS gives the VStrom an unfair advantage. I have tested the ABS in both wet and dry conditions finding it reliable in both. It tested at 1.05g using Dynolicious on the iPhone, vs only 0.82g for the Versys.

I am replacing my Versys with a VStrom, as I prefer the range of parts available, ABS and the different feel especially on the highway. The Versys is more fun to ride round town, if you can ignore the issues.

Most interesting. My next bike will have ABS methinks. I have no delusions about how good my riding is. If I can concentrate 5% more on traffic cause I don’t have to worry about braking, that’s a good thing.

My last significant off happened emergency braking into a roundabout. I thought it was clear, then a car with right of way came out from behind a blind fence. It was far too late to wash off that much speed, I swore I was going to have him hit me. As I braked and turned, the front wheel crossed the usual oily patch where cars drop oil on the centre of the wheel track. Presto – down she went, and I know how to cadence brake. I’m not good enough however to brake 100%, unlock for 0.5m and get fully back on again when trying 100% to avoid a car. ABS would have been fast enough. It wouldn’t have avoided the situation, but it may have been enough to keep the bike upright.

Rethink your Lid

Buying motorcycle helmets used to be easy. Plastic was crap, Fibreglass was good, Kevlar / Carbon was best. If it was a Shoei, Arai or Bell it was good, everything else was only OK.

BUT – interestingly enough, every single helmet you could buy had passed the crash test standard, so the better / worse was opinion, nothing more. In Australia this is an Australian Standard (similar to the US DOT standard, and many others). Really, it’s a “minimum”, everything on the market is better than the standard, it’s just a question of how much.

There was a defacto “better” standard – Snell. This was only issued to the “best” helmets, so if you cared, you bought a helmet that also had Snell certification.

Well now there is something better. The UK govt has setup a research and testing laboratory to test and rate motorcycle helmets like they crash test cars – with a star rating. You’ll find it at http://sharp.direct.gov.uk/ 

The testing is based on the new EU standard ECE 22.05 and discussed on webbikeworld.

I just bought a new Shark RSR2 to replace my aging Arai Qantum(1996). The new Shark is comfortable, quieter than the Arai on my head, and has a 5 star rating.

I prefer the new EU standard over Snell etc after reading this debate on MotorCyclistOnline and the testing they did. The base concept is that the Snell standard is very tough, and a tough helmet is not as soft and squishy. Soft and squishy is more likely to be useful to you in the accidents you are most likely to die from. The more serious accident that the Snell rated helmet is designed to protect your head for, will leave you dead from other injuries and with brain damage anyway.

Of course nothing will protect you from those big ones that just leave you dead.

This is some of the best discussion of motorcycle helmets and testing I have seen anywhere. It certainly made me rethink a lot of my assumptions.

Basically, do you want a tough helmet, or a soft and squishy one. I’m thinking soft and squishy is probably best.

Here is the testing and analysis http://motorcyclistonline.com/gearbox/hatz/
