Micro Speed Valve(M.S.V.)について

Damping force changes as oil flow bypassing needle valve changes. M.S.V. system generates damping force at the separate valve placed at the bypass flowing through the needle valve.


Adjusting the knob to softer setting causes unnecessary decline in damping force generation at low speed and worsening of steering response as a result. Use of M.S.V. prevents decline in damping force generation even with the knob set to softer position, thus improving steering response and traction performance.

Concept: INCREASES low-speed rebound damping force at softer setting...to provide sterring response

Ohlins DFV
[ PRODUCT TESTING | OHLINS DFV MODEL ] J.D.M. OPTION INTERNATIONAL

With the use of 3 channels on both the compression and extension cycle sides, the control of the attenuation of the moment at the beginning of the shock stroke is possible. Before the main valve starts to move, the sub-valve releases oil pressure for an overall comfortable ride.

Concept: Low Speed Blow-off valve? REDUCES low-speed REBOUND damping off bumps for the wheel can follow the contour of the road, thus increasing ride comfort

DFV seems to REDUCE the low speed rebound damping (after a bump) so the spring/wheel can rebound faster and follow the contour of the road after the bump, and avoid crashing into the road (which gives the harsh ride)


Here is a blog on Ohlins DFV - comfort seems OK

Tracking: DFV

There is no information on how good the steering response is on a DFV

Here is Ohlins DFV on a DC5 at Sepang

Looks like TEIN MSV only increase the low speed rebound (when damper is set to its softest) to avoid a floopy steering response, when the damper is set to its softest...

There needs to be a suspension shootout

TEIN MONOFLEX at it softest:test steering response vs Ohlins DFV

TEIN MONOFLEX at is hardest - COMFORT test on the road versus Ohlins DFV


TRACK TEST - Ohlins DFV versus TEIN Monoflex.


Comment - Ohlins doesnt have EDFC. MOTON - pls post you views, knowledge and experience

Moton Suspension Technology

Their web-site days they use a blow-off valve Very smooth over Curb stones, car is easy to control. saves drive shafts, wheel bearings etc.

The 4-way Adjustable Moton Damper features 15 positions of high speed bump adjustment, 6 positions of low speed bump adjustment, 15 positions of high speed rebound adjustment and 10 positions of low speed rebound adjustment. The low speed bump adjuster is very effective in helping to control body roll while adding to turn in and is effective in controlling pitch and squ
 
The blow off valve is designed to handle the large fluid displacement caused by the 22 mm O.D. Piston rod and responds to the smallest movements of the rod. The blow off valve is spring loaded with Belleville washers and by turning on the adjuster knob preload is forced on the blow off valve. Increasing the preload on the blow off valve creates higher compression damping.

Rebound and compression double valve stack, non pre-loaded


The rebound and compression stack are non pre-loaded and build up in two phases.

The primary stack consists of a main valve with a diameter of 34 mm (rebound) and 36 mm (compression), supported by valves decreasing in diameter according to the damper force requirements. This is the low velocity area of the damping,

The secondary stack is separated from the primary stack by a small shim of 0,15 mm thickness and a diameter of 21 mm. The secondary stack limits the opening of the primary stack. So by changing the composition of the valves damping forces can be increased or decreased. The secondary stack is the mid- and high speed area of the damping.

The MOTON damper is able to carry part of the weight of the car, permitting the use of softer main springs
 
I think TEIN created the MSV to combat the problem most TEIN shocks are known for which is being VERY linear, Ohlins (and moton) are in another class, TEIN will never be able to compete with Ohlins in my opinion. There two features are not the same but seem to have been created for the same purpose, which is better? Who knows, but if i had to wildly guess i would say Ohlins easily.

Keep in mind that these attempts to increase low speed comfort are not exactly what you think they may be, these are not for street situations. Instead consider that racecar drivers fatiuge over time, they get tired of fighting the stearing wheel, of all the bumps and the extremely stiff suspension, also its harder to control very stiff cars on bumpy tracks but with the MSV or DFV this may be a bit more manageable.
 
ive not really read above in detail but as blinx says ohlin and moton are at high end of suspension wheras tein is prob average (more well marketed than anything)

have you priced up moton ? usually as dear as suspension gets and 99% of users are involved in racing

Yup - its 10X more expensive (without springs) than TEIN Monoflex

Yes. MOTON is 10x more expensive than TEIN monoflex.

Ohlins DFV (Japan) is 1.3x the price of TEIN
 
would the monoflex be better then the flex (dual tube) for a low daily driver on bumpy roads?
