aku sebagai org baru disni nak kongsi kepoweran motot nie
aku pernah pakai TZR250 tak sampai sebulan,pakai RGV250 pun tak sampai sebulan.
RGV250 vs TZR250 kelajuan- motor nie kalo nak dibandingkan dengan tzr250,motor nie lagi laju la dari moto tu.. sebab tahun dier production pun tahun 90an.kalo tzr250 thn 80an lawan ngan thn 90an memang la takdinafikan.tapi kalau ikutkan memang sama2 lahir tahun 90 an pun,memang tzr250 tak boleh kejar rgv250 sebab dier buka 2 power valve.
Kemantapan tzr250 dgn rgv250 kalo nak dikomperkan handling dia,masing2 ada cara tersendiri.ia juga bergantung pada org yg bawak motor tu juga.kalo bab handling nie aku rasa kedua2 motor nie boleh tahan sama gakkle...
Spare Parts Tang spare parts plak.,..kena tanya otai 1kt...hehe...dier banyak stook... kalau ikut betul2,spare part tzr250 nie boleh dapat lagi...kalo nak dihitung mcm 4/10 la... kalo rgv nie spare parts bole masuk aprillia250...lagipun dia tahun 1990. kalo nak dihitung mcm nie 7/10 la...
bagi otai2 sumer kalo ader nak komen...sila la komen...itu berdasarkan pengalaman aku dalam bidang permotoran....
aku takde pengalaman ngan tzr atau rgv tapi boleh la nak menolong...
saiz... rgv lebih kecil dari sp/spr...untuk rider yang tinggi macam aku memang tak kena la kalo pakai rgv..sp/spr lebih sesuai....riding position tu penting..takde la cramp nak membongkok
aerodinamik... saiz rider jugak jadi faktor penting...contoh yang nampak....kocik kalo naik rgv memang ngam..sesuai sangat..tapi kalo naik spr nampak macam kocik sedang bertenggek kat atas motor tu....
handling... dua-dua fork usd...handling memang best...faktor penting nak kasik lagik best adalah jarak dari seat ke handle bar dan juga jarak dari seat ke footrest....tu yang berperanan samada kaki selesa kepit tank mahupun kaki dok atas tank...tak pon body position bila tunduk atas tank...samada siku boleh lock dengan lutut atau tak pon penting untuk handling...
maintenance... rgv boleh masuk barang aprillia rs250 pasal aprillia tiru enjin suzuki untuk keluarkan model rs250...ada jugak pomen malaysia masuk part ap 250 dalam rgf250...jadi takdela sangat isu sparepart takde..cuma mahal la sket..biasala...buatan itali....kalo tzr spr 3xv..setakat yang diketahui sakit sket pasal nak kena pakai barang ori gak..takleh nak kacuk barang lain..tapi tzr sp 3ma boleh lagik kacuk barang lain...isu sparepart memang leceh la sket...tapi masih ada kalo rajin mencari...sabar tu penting
Introduction The RGV250 (Gamma) is a high performance sports bike which had a great number of its features and design clues based on the Grand Prix technologies and ideas of that time. It is a race-replica based on Suzuki's 250cc GP bikes from 1987 to 1998. The motorcycle incorporates many features taken directly from Team Suzuki's Grand Prix winning RGV Gamma V-4 racer. This motorcycle replaced the popular RG250 Gamma which employed an alloy frame with a two stroke parallel twin engine. The bike produced over 50 bhp in a narrow power band between 8,000 to 11,000 rpm. Weighing in at 128 kg (282 lb) (1989) to around 140 kg (309 lb) (later models) dry weight, this motorcycle has an excellent power to weight ratio, with good acceleration and sleek aerodynamic producing a relatively high top speed.
The top speed of a standard RGV250 is around 130 mph (209 km/h) when ridden by an average weight person. It has a 0-60 mph (97 km/h) time of around 3.7 seconds, again, when ridden by an average weight person.
This motorcycle's engine performance is not very inspiring at engine speeds under 6,000 rpm, due to the two stroke engine power delivery of a relatively narrow power band. However, once the engine is revved over 7,000 rpm, the power delivery characeristics transform the from a street bike to a pure bred track sports bike.
Due to its light weight, engine characteristics and cornering capabilities, it is particularly suited to the track, compared to other motorcycles of similar engine capacity.
[edit] Model Designation and Power All RGV250 models, with the exception of the Japanese domestic market's version (restricted to 40hp), make 50+ hp. The model designations are:
VJ21:1988-1990: quoted power; 1988=58hp, 1989=59hp (90° V-Twin, i.e. the space between the cylinders) VJ22:1991-1996: quoted power; 1991=62hp (revised engine with more power, still 90° V-Twin) VJ23:1997-1998: quoted power; 1997=70hp (from the very special 'SP' model (sports production) with new 70° V-Twin engine)
[edit] Technical The VJ21 was the first RGV250 production motorcycle available in Japan in 1988. Technical aspects were:-
Alloy Beam frame 90 degree, water cooled two cylinder two stroke V-Twin style V engine (separate crankases, single in-line crankshaft) 2 piece exhaust valves which have two positions - open and closed Dual Reed valves, with Suzuki Intake Pulse Control system (SIPC), similar to Yamaha Energy Induction System (YEIS) but avoids patent issues 32mm Mikuni Carburettors on 88/89 models, replaced with 34mm models with single air bleed on 1990 model 17" front, 18" rear three spoke alloy wheels with twin 296mm front disc brakes and single rear Front suspension is conventional 41mm damper type telescopic motorcycle forks (not cartridge) Suzuki Pointless Electronic Ignition (PEI) analogue ignition system on 1988 models, replaced with digital system on 1989/90 models which was a predacessor to the SAPC as fitted on the VJ22 Dual, side-by-side expansion chambers
The VJ22 machine relied heavily on the VJ21, but had the following improvements:-
Suzuki Advanced Power Control (SAPC) computerized engine management system 3 piece exhaust valves with three positions - closed, half open and fully open 34mm Mikuni carburettors with dual air bleed system 41mm inverted cartridge type telescopic motorcycle forks modified swing arm fitted to permit both expansion chambers to be routed on the right hand side 17" rear wheel 310mm front discs In addition, a restricted VJ22 model was available in Japan as Sports Production (SP) model, which came with dry clutch and close-ratio gearbox as standard. A later SPII model reverted to standard wide ratio gearbox with dry clutch.
The VJ23 uses a totally redesigned engine with few interchangeable parts with the early models, and has a dry clutch and close-ratio gearbox as standard.
[edit] Reception In the UK, the motorcyle press reponded favourably to the VJ21. However, the initial VJ22 models had a design flaw in the 'improved' 3 piece exhaust valves. This was corrected on later VJ22 models, but still needs to be inspected regularly. The VJ23 is not known to have powervalve issues.
[edit] Riding Experience These motorcycles are not particularly suited to carrying pillion passengers on long rides, due to its race orientated design, detracting from comfort. Hence, touring is also not a strong point of this model. In straight line acceleration, the RGV250 is faster than most other 250cc two stroke and four stroke motorcycles, including the RG250, TZR250, NSR250, Kr1, Kr1-S, FZR250, CBR250RR, GSXR250, ZX250R, Hyosung 250GT and CB250.
The Aprilia RS250 is related and uses a modified RGV250 VJ22 (90° 2-Stroke V-Twin) engine.
Aprilia bought engines from Suzuki (which were fitted with Aprilia branded castings on the timing and clutch covers), then fit their own expansion chambers, barrels and ECU. There were also external differences in the cylinder head castings, but no internal differences have been noted.
Production of the Aprilia RS250 is thought to have ceased in 2003, with end of engine production by Suzuki.

Led astray by the lure of wild powerbands and wilder tank-slappers we present: KR-1S, RGV250M, TZR250 and, just for old time's sake, RD350LC-F. We trundled them across the fens, hurled them up the Cat and Fiddle road (the A53 between Buxton and Mace), sat them in a traffic jam in Manchester and finally whupped them round the ultra-tight Three Sisters race track near Wigan. We even brought most of them back again.
YAMAHA TZR250
They wouldn't let it lie
Well, actually, they would've let it lie, but we wouldn't listen. The TZR is now out of production, and Yamaha aren't keen to push the remaining stocks. They would rather let them slip quietly away without any fuss that might detract from the almost certain 1992 launch of the all-new TZR.
It's a shame really, because there is life in the TZR yet as road bike. It may no longer be able to cut it on the track, but the combination of stable handling and reliable power means it can still keep up on all but the fastest roads.
For any model to survive so long virtually unchanged is testament to the soundness of the original design. Rupert: 'It's the perfect mix of race technology and practical useability.'
On the Cat and Fiddle and surrounding roads the TZR was probably the easiest to get the best from. Chassis, brakes and power harmonise so well that the rider can concentrate entirely on the road ahead, confident that the bike won't spring any nasty surprises. Stephen: 'I really don't think you can fault it - you can slam it into corners with the brakes full on and it'll still go round, with the only protest coming from the tyres.'
Where the RGV would sit up violently under mid corner braking, and the KR-1S felt as though the front wheel would tuck under, the TZR stayed gently on line until the rider decided what to do next. This is the sort of behaviour that can save your bacon on unfamiliar roads, especially when they are flanked by frightening drops.
On paper at least, the TZR is the slowest steering of the 250s, sharing its rake and trail figures with the 350 powervalve, and it may be this which helps give straight line stability that's no more than a dream for KR-1S owners. Cresting small rises on the Cat and Fiddle, or launching off yet another cratered bump on my ride across the fens to work, the TZR would lift its front wheel slightly, give just a little wibble, then smack rather satisfyingly back down to earth before continuing on its way as though nothing had happened.
On the same fen roads, the KR-1S would go from lock to lock before settling down, and meeting another bump before the steering had sorted itself out was a deeply distressing experience.
At Three Sistefs the TZR's tyres quickly became the limiting factor. Yamaha aren't doing themselves, or the bike, any favours by letting it out of the factory with tyres so far behind the rest of the bike. Trevor: 'The standard tyres are disgusting.' This was something we all agreed on, although Rupert was more polite: 'The tyres grip OK but offer nothing like the feel and grip of the RGV/KR-1S. Aftermarket stickies would improve things but it'll never quite be up to the latest standard. It'd be enough for most people though.' By all accounts a change to Avon AM22/23 rubber does the job nicely.
Lousy tyres aside, the TZR feels totally at home at the track, though it rapidly runs out of ground clearance - if you don't hang off as far as possible it feels as though the footrest is about to dig in and lift the whole bike off the floor. The braking lacks some of the awesome ability of the newer 250s - 'Plenty of power, plenty of feel. But the KR-1S and RGV have even more.' - Rupert. It is easier to use all that's available, though, and a panic application doesn't necessarily spell disaster. Trevor: 'The single disc works fine, but requires further clenching of the fingers after the initial grab.'
Stepping onto the TZR directly after the RGV, it's easy to see the Yamaha as crude and unsophisticated, but the fact is that the basic package is so good it doesn't need frills. Stephen, commenting on the suspension options, pointed out: 'There's not much adjustment because it's not needed.' The best thing to do with a TZR is to set the rear preload to suit your own bulk, then get on with riding it.
Ten minutes in town and the TZR shows the other side of its character. Apart from some mild clucking between 5 and 6,000 revs, when the powervalve can't decide whether to open or close, the motor is utterly docile in traffic. It puts up with extended low-speed running without complaint, all the controls and switchgear are sensibly designed and easy to use, and the well-shaped seat and relatively upright position make it easy to trickle through jams where the Kawasaki and Suzuki produce a wrist-heavy weave.
Trevor summed up the joys of long-term TZR ownership: 'More friendly than the others. Starts first time, the mirrors are useable and the seat is comfortable up to the first tank refill' If that doesn't sound very far, bear in mind that the other 250s were probably designed by an unemployed set designer from a Japanese TV game show specialising in personal humiliation. Stephen added: 'The TZR is easy to clean, good pillion seat, luggage can be carried, lasts for ages. Bought by sensible people.' Except for you, Stephen.
If all this seems to be singing the TZR's praises rather too loudly, then I apologise, but Trevor was its loudest critic, and the worst comments he could make were to suggest that it was under-geared (hitting peak revs long before the timing lights at Bruntingthorpe), and to point out a grabby clutch. The TZR is dead. I wonder if the new one will live as long.
v4 semput mmgla rgv bole mkn...cuba kena yg tiptop tgk....mmg mimpila rgv tu...v2 vs v4..dr segi pikap mmg rgv boleh pegi dlu sbb rgv lbh ringan(faktor power 2 weight ratio). tp bila dh topspeed..sndri pikirlah..250 vs 500...kalo nk diikutkan,mane bole nk compare antara 2 model ni..masing2 berada dlm kelas yg berlainan..rd500 vs rg500 barula btul..kalo ikut bike review zaman dlu2,mmg rg500 menang topspeed berbanding rd500,tp rd500 menang dr segi styling dan handling..hehehe..
kalu pakai pari nanti buleh la samo dengan otai1kt... pari nie pon mantap.. tengok jela macam mane pari otai1kt... mantap tu.. kalau pergi ride mesti kat depan.. x terkejar yang lain..
abang rdowner...apa perbezaan diantara TZR250 1KT ngan TZR250 2MA?pastu plak sebagai nak buat projek...apa nak ditambah supaya performance TZR250 1KT sama macam 3DP?
1kt xde sidestand switch,2ma ade..that mean wiring loom adela sikit beza....panel meter,monoshock,sidemirror,colour scheme......bla bla bla..pendek kate tula serba sedikit beza antara 1kt/2ma....
